Philosophy of Care
Substance use disorders are disorders of brain function with emotional, psychological, behavioral, spiritual, physical and social manifestations. Treatment is guided by current clinical research, patient preference and availability of resources. Everyone’s needs are unique and care is a collaborative, ongoing, adaptable endeavor.
Dr. Leamon is an Addictions Psychiatrist who provides office-based outpatient treatment for Substance Use Disorders, including medication-assisted therapy for Opioid Use Disorders with buprenorphine or naltrexone. He works with an integrated team from social work, pharmacy and nursing.
Dr. Leamon's academic interests are in substance use disorders, systems of care and medical education, but since he mainly works collaboratively, they are often swayed by what his friends are interested in convincing him to do.
