If you are new to Commerce and are looking for a good family doctor you can't do any better then Dr. Marsburn.
His office is easy to find across from the hospital.
He and the other doctors in this practice treat each one of their patients like they are in their own family. He takes time to answer questions and you never feel rushed.
Take a book when you go to the waiting room. There isn't much to read there and your wait can sometimes be long... but the service is worth it.
