Meet our professionals

Dr Edward Carlstrom

Edward Carlstrom, MD

(also known as “doc Ed”)

I’ve been practicing medicine for 45 years, after graduating from St Louis University with a Doctor of Medicine degree. I worked in Urgent Care for most of my career, but during the past 15 years my specialties are addiction medicine, psychiatry and pain management.

I am patient oriented, doing the best for the patient and not for my own financial gain. I treat opiate addictions with Buprenophine (Suboxone) and injectable Naltrexone, and I have extensive experience treating anxiety, depression and pain management.
