Dr. John B. Casper is a native New Yorker who grew up in Idaho. In his  spare time, he enjoys skiing, kayaking, new adventures, joking-around, and spending time with family and friends.

John Casper graduated with honors and received  the Doctor of Medicine Degree from the University of Washington School of Medicine. Following medical school, he completed eight and a half years of graduate medical training in three specialties. Dr. Casper maintains Board Certification in Addiction Medicine, Internal Medicine, and Anesthesiology. He has accumulated over a decade of experience in the treatment of addiction and mental illness.

During years of practice in primary care, Dr. Casper realized that our difficulty controlling unhealthy behavior is the greatest barrier to wellness. Believing that addiction's socioeconomic impact is greater than that of all other diseases combined,  and that treating addiction will provide the greatest health benefits for those affected by the disease, Dr. Casper eventually chose to focus his practice in the field of Addiction Medicine.  

Dr. Casper is accepting patients for the treatment of addiction and substance use disorders. He also provides medication management for mental illness and co-occurring disorders, formerly known as "dual diagnosis".
