Beginning of our history

New Horizons Medical, PC was founded in 2009 as a private physician group dedicated to providing the safe prescription of buprenorphine (Suboxone) to the patients engaged in serious recovery efforts from opiate dependence. Since then, along with the other services, we provide compassionate care to all individuals regardless of the reason or history or the addiction.

Our history

Originally from Latvia, Dr. Antonevich studied, volunteered, and worked in many countries around the globe. He was a highly professional and compassionate person who dedicated his life to helping people in need.

Dr. Antonevich volunteered in Haiti after the devastating earthquake of January 12, 2010.

After this devastating event, his wife Oxana Antonevich took on the role of New Horizons Medical’s President.
