Dr. Lahey knew he was going to become a psychiatrist at the age of eighteen when he began working with chronically mentally ill adults in the group home setting. This work continued throughout his college years while attending The College of William & Mary in Williamsburg, Virginia, where he fulfilled his pre-medical requirements and graduated with an interdisciplinary major in biological psychology. Following college, he worked at University of Virginia Hospital on the psychiatric unit. After two years, Dr. Lahey enrolled in medical school at St. George's University. After medical school, he completed his residency training at the University of Kansas Medical Center, as well as his two year fellowship in child & adolescent psychiatry. Throughout his training, he established a patient base through his moonlighting work with an underserved population in Southern Iowa. And, upon finishing his fellowship, he served as their medical director (Community Health Centers of Southern Iowa) for two years before transitioning into private practice. During that transition, Dr. Lahey managed the psychiatric needs of children in residential state custody through Kaw Valley Center (KVC) for approximately one year. Lastly, Dr. Lahey holds additional certification for treating opiate dependence in the outpatient setting, enabling him to provide a growingly needed service.
Dr. Lahey is one of the few psychiatrists who treats patients of all ages, which has grown his understanding of family systems and intergenerational dynamics. Because of this work, Dr. Lahey developed Binary Psychology in response to his insight into the two-part consciousness of the thinking mind. His understanding of how children perceive and form beliefs provided essential insight into the nature of the parent-child relationship. And his elaboration of how changes of consciousness occur and symptoms preceding such changes gives his model a growth oriented, curative potential for patients.
