Dr. McMullen is the best doctor I’ve ever been to. She was so thorough and saved me from absolute agony from misdiagnosed osteoarthritis. Quick to diagnose and got the ball rolling. I’ve had three surgeries now and pain free. She’s amazing!

I have used Dr. McMullen for several years. I appreciate she takes the time to listen to me. They never leave me sitting in the waiting room for hours like most doctors. She explains things very well and has always been kind. If you are looking for a down to earth Dr. that knows her stuff give her a try.

Dr. Susan McMullen has been our family of three , physician. Let me just start by saying she has always been fantastic! We have had her for going on approximately 10 years and never been happier.She doesn't rush you put and even if it looks like lobby is full she still has a smile.She one time caught my husband's Lyme disease so quickly with meds that we knew how smart she is. She never scolds one even if they need to be. She is sincerely caring and to us a perfect example of true kindness . We just love her.

Today was my first visit with dr Susan McMullen and I must say she is the best doctor I have ever been to. She listens to what you have to say and explains things very good. She doesn’t rush to get out of the room. Very friendly and polite and the staff is amazing. I would highly recommend her I moved here from Garland and have tried several here and I just love her. Glad I found her !! Patricia Carroll

I truly respect Dr. McMullen. She has been our doctor for years. She listens, she cares, she takes quick and appropriate action to resolve health issues. Thank you, Dr. McMullen for being the doctor and person that you are.

Dr. Susan C McMullen is the best doctor I've ever had. She's been my doctor for several years. She listens to what you have to say and she takes time to ask questions, examine you, and answer your questions. She never makes you feel like you are being rushed. She doesn't just see you as a patient, but a person. If you are sick you can usually get in touch with her over the weekend using her answering service. And during office hours, you can usually be seen the same day or the next day. If there is an emergency, the ER is located in the same building.

I was a pt of Dr.Mcmullins ,its been 2 yrs since i have seen her due to moving away,I have searched and searched for a dr like her and no luck.She is the only one that gets to THE bottom of my issues.I called to try to get in to see her again and was told no because its been 2 yrs and i have no immediate family that sees her..What does that have to do with my health? Really upsetting even though i have outstanding ins and was a former pt.
