Patient Comments (7)
Dr. Marshall has been my cardiologist for over 4 years now. He is one of the best doctor's I have ever had because simply, he cares and had the knowledge and professionalism to back it. I felt as though I was the only patient in the world and it actually made me try harder to survive, live and thrive. The office staff is friendly and I have had no issues with scheduling or prescription refills. I highly recommend this office for yourself and your loved ones. You will be in good hands!
Brett, thank you so much for your positive comments about Dr. Marshall! Your kind words and recommendation mean the world to us and we are happy to have earned them. Thank you again and have a fantastic day!

I was treated horribly by Dr. Marshall's office recently while a cardio patient at TMC. I would not recommend using him and would not trust him.

I was sent to the emergency room for chest pain and Dr. Marshall was brought in. He was very informative and took his time explaining what was going on. His staff has always been friendly and helpful. He's been my cardiologist now for nearly 10 years now and I am doing so well I only have to see him yearly.
Paula, reviews like this give us motivation and help us ensure we continue to provide high-quality care. Thank you for taking the time to let the world know about your positive experiences with Dr. Marshall. Have a wonderful day!

I have been trying to get my mom into see Dr Marshall. However, They need paperwork...then when you call to find out if you can email it to them...NO REPONSE. This is very unprofessional and reflects badly on the Dr. If this is the way things are going to start out then maybe I should find some other Cardiologist to take her too.

My husband has been a patient of Dr. Marshall's for several years. We both feel as if Dr. Marshall doesn't pay enough attention to his patients. We have spoken with others who agree with us. He glad-hands you, tells you that your heart is great, and shortly thereafter you are having open heart surgery for something he missed My husband had a quadruple bypass in February, did well for a while, then he began to decline. He quickly became short of breath, Dr. Marshall never ordered pulmonary tests.

Dr. Marshall is the only heart doctor that my wife and i want to see(we would see Dr. Turner also) he is in with Dr. Marshall. Excellent doctor. Wonderful man.

Went to TMC with chest pains had to have heart cath and stint put in. Dr Marshall went through my wrist and explained everything in detail to me and my family. I would definitely recommend him to anyone. Very comfortable to talk to does not rush you in anyway and listens to you. Just went back for my visit in his office and thank God I don't have to go back for 1 year. Thank you Dr Marshall!!!!
