Gary Ruelas, D.O., Ph.D - Founder

Gary Ruelas, D.O., Ph.D

Dr. Ruelas holds doctoral degrees and is licensed to practice in both medicine and psychology. He approaches his patients by gathering and analyzing data differently from other physician’s moving away from a disease model to a holistic functional model. He looks at the molecular, genomic, psychosocial, cultural, behavioral and even 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.

PSYCHOLOGY: 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 in his practice as well as providing Neuropsychological Assessment as needed for his patients.

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.
