Dr. Gary Ruelas, D.O., Ph.D.

Dr. Ruelas looks at the molecular, genomic, psychosocial, cultural, behavioral, and especially the spiritual path, taking each of his patients through bridges not yet crossed and transcending the connection of the mind, body, and spirit. His approach is unique, transforming, refreshing and progressive. He takes the time to understand what led up to the current situation, what may be contributing to the recurrent problems and outlining a plan to begin remedying one’s difficulties.

He understands Immunology, as a branch of biology that studies the physiological functioning of the immune system in states of health and illness. Dr. Ruelas looks at both states and attempts to understand the missteps that occur in disease while working to optimize health. Such concepts as autoimmune disease, inflammatory and autoinflammatory dysfunction, hypersensitivity, deficiencies to underscore a few. It is a fabric of studies that is interwoven in the fields of oncology, endocrinology, rheumatology, virology, bacteriology, parasitology, psychiatry, and dermatology to list a few. But in and of itself it is a system within the body with no known location. There are components that might be outcomes and no one variable or variables are the system itself. Therefore, like the mind, it lies somewhere between matter, which plays a major role in the quality of life and maybe an outcome of the balance of energy our body mind and spirit interface with.

Dr. Ruelas completed his doctoral dissertation, studying the Neuropsychology of Attention Deficit Disorder and Dysthymia in Children. During his doctoral program he also studied psychoanalysis, and practiced child psychoanalysis for a number of years as well as providing Neuropsychological Assessment as needed for his patients. During his early program(s) Dr. Ruelas went on to study clinical hypnosis with Milton H. Erickson, M.D. having personal tutorials with him and, under his teaching, became proficient in the use of direct and indirect hypnotic techniques. Dr. Ruelas also studied with the Anthropologist Gregory Bateson and studied system theory and Cybernetics with the physicist Heinz Von Forester, Ph.D. He completed post-doctoral work with the Milan Group at the Institute for Family Studies in Milan Italy at the Universita Degli Studi Di Milano with the Jungian Analysts Gianfranco Cecchin, M.D. and Boscolo Luigi, M.D.

Dr. Ruelas went on to form the Orange County Society for Ericksonian Psychotherapy and Hypnosis and brought together such great clinicians as Kay Thompson, DDS, John Weakland, Ch.E., David Cheek, M.D., Andre Weitzenhoffer, Ph.D., Humberto Maturana, Ph.D., Gianfranco Cecchin, M.D., amongst others.

Simultaneously Dr. Ruelas worked in the public mental health systems. First with a grant from the National Institute of Mental Health where he helped to create a residential treatment facility for recovering addicts transitioning out of the penal system. He then went on to work with the Department of Mental Hygiene, State of California working with adolescents who had been placed in the State Hospital system for behavioral and emotional difficulties. From there Dr. Ruelas went to work with the County Department of Mental Health, initially in the Chemical Dependency Program working with inpatient detoxification of opiate users and providing outpatient counseling to them and their families. Later he continued his career in the Adult Mental Health Department where he worked in Crisis Management, Out-Patient Services and After Care Programs, dealing with patients suffering from severe mental illness. He later became one of the Service Chiefs for the Children and Youth Mental Health Service program for the County, managing outpatient and inpatient care for children and youth of the County and working closely with the Departments of Education and Social services before leaving to full time private practice.

Though Dr. Ruelas started off and has always worked with children, his study of the brain, mind and spirituality has made him knowledgeable to help individuals of all ages and walks of life. His work has expanded into the cellular biology of the body and mind and has expanded into work that is transpersonal and transforming. He has always been dedicated to children and youth and to the treatment of substance abuse disorders and how the use of chemicals affects the molecular structure of the brain both in children and adults. His background in Neuropsychology offers him a broad perspective when dealing with each individual exclusively.

In 2003, Dr. Ruelas went back to his early training and in conjunction with the Milton H. Erickson Foundation, formed the first Ericksonian Integrative Medical Institute (EIMI) using the work of Dr. Erickson and applying Dr. Erickson philosophy, not only to psychology but to medicine. The EIMI program serves as a prototype that can enhance the unconscious process of each patient despite their symptoms or physical challenges. Dr. Ruelas advocates using the unconscious mind at all stages of healing in preventive, restorative and addiction medicine and in psychology.

After fifteen years of public service, Dr. Ruelas left his position the public health and went back to school and obtained his Medical Degree in Osteopathic Medicine completing his residency in Family Medicine. During his final year in residency, Dr. Ruelas served as the Chief Resident of his program. He soon thereafter pursued post-doctoral studies in Integrative Medicine. He obtained Board Certification with the American Board of Integrative Medicine and completed training with the Autism Research Institute obtaining the Highest Level of their DAN physician management program.

He is presently in full time private practice as an Integrative Physician practicing, functional Mind-Body-Spiritual Medicine, working with all ages while he continues to have specialization with children, adolescent, and addiction medicine. He serves as the Medical Director and Clinical Psychologist for the Integrative Medical Institute and the Ericksonian Integrative Medical Institute.

One of his areas of medical expertise is Preventive, Integrative/Functional, Addiction and Mental Health Medicine. He is interested in imbalance and deficiency of essential elements of the body than of diseases. He utilizes biological studies to determine what if any essential elements, nutrients, anti-oxidants or neurotransmitter precursors are either out of balance or depleted from the body. Dr. Ruelas will look at levels deeper than depletion, investigating the integrity of the cell membrane and intracellular organelles themselves to determine if cellular dysfunction exists. Through this approach, Dr. Ruelas has helped individuals regain their energy, vitality, and minimize and even overcome a disease process. By investigating a matrix of root causes in the diagnostic and therapeutic process he opens up a different way of treating complex and chronic states of stress in order to rebalance the lives of his patients, providing them once again with energy and vitality. Dr. Ruelas also provides detoxification for a number of different problems ranging from various toxins such as heavy metal, to chemical dependency. He is certified to prescribe SUBOXONE. (Read more about Suboxone therapy).

Dr. Ruelas remains very close to his training as a Clinical Psychologist, bringing into his care the emotional and mental health life of each of his patients. At the Institute where he practices he is surrounded by colleagues who are also engaged in the practice of Mindfulness and Integrative Mental Health Care. The Institute makes available to their patient’s psychotherapy, mindfulness treatment, yoga consultation, and myofascial massage therapy.

He has presented nationally and internationally and has been a recognized speaker at the International Conference for Ericksonian Psychotherapy and Hypnosis. He founded the first Ericksonian Integrative Medical Institute and continues to present at national and international conferences on Ericksonian techniques in psychology and medicine. His areas of psychological expertise include developmental, attention, learning and mood disorders. He has training in psychoanalytic, CBT and system modalities. He is trained in the use of hypnosis, NLP and in marital and family therapy. As a Neuropsychologist his expertise is in attention deficit, cognitive and pervasive developmental disorders and he is DAN certified. He uses both neuropsychological assessments the QEEG analysis and neurofeedback when working with patients.

Dr. Ruelas has been working in the field of Child Health for over two decades. His background as and Child Analyst and Child Neuropsychologist gave him the foundation to work and understand the complexity of PANS/PANDAS. His background in Public Health gave him a deep appreciation for a multi-disciplinary multi-modal form of care necessary in complex cases. His background in the family system also gave him the tools to help support family members during this complicated path. As a physician in family medicine and his fellowship studies in Integrative/Functional Medicine also offered him a spectrum of tools to deal with the challenging cases of infectious diseases. As noted above, Dr. Ruelas’ study of disease and infections at a cellular level focuses not only in the elimination of pathogens but in the foundational restoration of immunity.

Dr. Ruelas holds a Ph.D. in Psychology and finished his Doctoral Thesis on the Neuropsychology of Attention Deficit Disorder vs. Depression in Children and Youth. He later studied psychoanalysis and went on to practice as a Child Psychoanalyst, working with Children and Youth in the Public Mental Health System. He served as the Service Chief for the Orange County Children and Youth Program west region area and later as a Service Chief for Children and Youth County Wide Inpatient Programs. He completed post-doctoral studies on family systems at the Universita Degli Studi Di Milano in Italy and has always continued to work with children with developmental and behavioral delays including but not limited to cognitive, behavioral, and emotional challenges.

Dr. Ruelas started working in Addiction Medicine, first as Assistant Director of an inpatient treatment facility for individuals with a known history of addiction coming out of the state penal system and transitioning back to the community. The program he helped to develop and worked in was funded by the National Institute of Health. Later he was an intake coordinator for the County inpatient opiate detoxification at the Brea Neuropsychiatric Hospital. He went on to treat and manage medically and psychologically complicated substance dependent individuals with dual diagnosis. Most recently Dr. Ruelas was appointed to be on the Board of Trustee for the America Osteopathic Association of Addiction Medicine (AOAAM), where he served as Trustee for two years. He has written and presented on the topic of addiction medicine locally and nationally.

Dr. Ruelas believes that many individuals who suffer from chemical addiction are gifted and have been overwhelmed with what their brains absorbed from their environment and other people. He has found while teaching individuals to manage their gifts, they are more easily able to transcend to health and give up the addiction they have had so close to manage their pain and disturbance.

Dr. Ruelas, while embracing the opportunity to detoxify individuals from substances they may be abusing, helps them to differentiate what are the real problems they may be facing that are perpetuating their disorders. Dr. Ruelas takes the time and has the inherent skill to expand beyond what most centers are doing to treat substance abuse disorder.

Dr. Ruelas has been recognized as one of the eminent doctors in the field of bio-identical hormones and is mentioned by Suzanne Somers in her books, Breakthrough, Ageless and Shout Out. He understands that hormones affect the body systemically, not just gynecologically. He understands and embraces that hormones have been in the body almost immediately following conception and remain in the body systemically throughout the course of life. He is intent on safely balancing all molecules of the body including hormones thus bringing the body to an optimal state of harmony.

Dr. Ruelas recognizes that we have been and are presently undergoing an evolution in consciousness, in our awareness, and he is making every effort to bring spirituality to psychology and medicine. Consciousness can be understood as an awareness of something more than ourselves. Dr. Ruelas embraces the concept that matter makes up only 4% of the universe and the rest is not visible to us. By learning to be open to this other intangible world(s) Dr. Ruelas believes healing is enhanced and quality of life is improved. Though many individuals confuse spirituality with religion, they block off this awareness. These concepts are not necessarily the same thing, though they can be integrated. By understanding the difference and coming to an alignment with your core self, and the energies around you, life may be dramatically improved.

Dr. Ruelas is completed a two-year program with the Center for Action and Contemplations in New Mexico, a program studying mystics and spiritual transformation through the teaching of the Bible with Richard Rohr, James Finley amongst others. He is also enrolled in Seminary taking courses toward a Doctor of Ministry (DMin) program with the Claremont School of Theology. He completed all of his Seminary course work in studying theology and spirituality and now completing his doctoral thesis.

Dr. Ruelas is active in his local community engaged in activity with various church leaders and churches, he has a strong faith and brings his knowledge and belief of God into his practice on a daily basis.

Amy Joy Smith

Amy Joy Smith


Amy Joy Smith is a Nurse Practitioner specializing in Functional Medicine at IMI. She is a renowned pioneer in the PANDAS front who at this time, limits her work to PANS/PANDAS cases, and takes a holistic approach to medicine with experience as a clinical nutritionist.

Amy Joy Smith

Amy Joy Smith

Amy Joy Smith is also the mother of an amazing child with PANDAS and a dedicated PANDAS awareness advocate.

As a PANDAS parent, Amy understands what it’s like to have your child just slip away one day and have no idea why, to go from doctor to doctor to doctor without answers, to live in a dark place with your sick child, and to lose everything to PANDAS. Even after all of that, her son, now 22, is a senior in college with a full merit scholarship and a great life ahead of him. She believes that potentially each and every child can heal from PANDAS/PANS with the right information and a huge integrative toolkit.

Amy believes that every aspect of her personal and professional background has led her to this most clinically complex, professionally challenging and humbling work–that of supporting children with PANDAS/PANS and their families, as well as those with Lyme-based infections and other immune illness. She puts everything she has into each patient’s process and is thoroughly committed to seeing an end to the pathetic gap in the diagnosis and proper medical care of children with PANDAS and their families.

Amy serves on the PANDASNetwork.org Board of Directors and was the lead organizer of the West Coast PANDAS/PANS Parent Symposiums in 2012 and 2014. She has spoken at a number of conferences and trainings around the country and abroad. Like many providers that see children with PANDAS/PANS, Amy works with patients from around the world.

Having been both the mother of a child with a long-lasting and oftentimes severe case of PANDAS and a provider since before much was known about the illness, Amy is comfortable interacting with the familial breakdown and personal isolation that stems from it. She takes extra time to address the mental and emotional well-being of not only her patients but those affected by them. She makes it clear that people do not have to explain their mental or emotional states to her, or worry that she will judge them or think they’re crazy as many providers less equipped to deal with it often do. Amy knows she never would’ve personally made it through her own son’s illness on an emotional level without the support of other parents just like her. She is honored to be able to give back to these families by helping their children get well.

Amy is a team player, often working in tandem with other PANDAS providers around the country and taking the time to reach out to and consult with non-PANS/PANDAS providers who want to learn more about it. She is grateful to now be working with Dr. Ruelas and other providers at IMI and believes they have much to add to the PANDAS story in terms of both unraveling and treating this complex illness.

Those who know Amy can see that she assumes a very high level of responsibility for more than just her direct patients.  Although she does have patients in 20 states and seven countries, she takes time out of her incredibly busy life of caring for others to do just that­. For instance, Amy reaches out to connect with other parents through social media and blogging. She was the Medical Advisor and co-producer of the Emmy award winning PANDAS documentary My Kid Is Not Crazy, working with American film director and associate professor at University of Florida, Dept of Telecommunications, Tim Sorel. She frequently communicates and works with schools to help them provide the most appropriate services and accommodations to her patients who need them, and last year gave an in-depth training to over 200 school nurses on the east coast on how to identify and support students who may have PANDAS.

Amy has practiced functional and nutritional medicine since the early 1980′s and has studied with a number of pioneers in the field.  She attended Syracuse University School of Nursing where she received her BSN in Maternal-Child Nursing, and all of her acute care and hospital experience is in pediatrics. While currently she is working with all ages of patients, Amy has a passion for working with children and teens. At the University of Minnesota, she was a Fellow in the World Health Organization’s renowned Adolescent Health Training Program Medical School, and in addition to being a Nurse Practitioner, has a Master’s Degree in Adolescent Health with a focus on Youth Development and Community Health. She loves educating patients and families and has extensive experience in community education and program development for families as well as vulnerable youth populations.

Amy is passionate about organizing to change public awareness and social policy so people live better lives on every front. She is on the Board of Directors of PANDASNetwork.org, a parent-based 501(c)(3) nonprofit organization dedicated to promoting PANDAS awareness, research, and advocacy.
