If you are looking for a great family doctor in St. Louis, check out Northway Internist. They have a great central location at Depaul Hospital. The staff is very friendly and always willing to help you. You can call with any questions and if you need to come in they can usually get you in right away.
There are several doctors in the practice but I specifically recommend Dr. Page. He has been my doctor for over 10 years and is just wonderful. He is always friendly and genuinely cares about his patients. I highly recommend them!
