Amardeep Mann, MD

Dr. Mann completed  medical school in India, and his main desire was to immigrate to the USA which has the best medical care in the whole world. That dream came true in 1992 and he moved to California at the age of 26. “I was fortunate to be accepted at University of Southern California in Los Angeles for my Internal Medicine residency and Cardiology fellowship. I started my private practice in Southern California and raised two kids. In 2015 I left California to pursue a less stressful lifestyle and provide care in rural America.”

After a few short stints with a couple of other jobs Dr. Mann found this opportunity in Roseburg and it is exactly what he has been looking for.

“I practice medicine with the latest guidelines and focus highly on preventive care. I practice what I preach and apply it to my personal lifestyle as well. I am board certified in Cardiovascular medicine and International Board of Heart Rhythm Examiners (IBHRE).  In my free time I like to exercise, play golf and love riding my motorcycle on our local windy roads.”
