What People Say About Dr. Gregory Seymour, MD
RecentHighestLowestMost Helpful

I have been a patient of Dr. Seymour for the last 5 years since I was diagnosed with a blood clot. He is very thorough and listens carefully. He explains everything so you won’t leave with more questions than answers. When I developed a second clot in February due to knee replacement surgery, the ER doctor consulted with him for my immediate care. I feel blessed to have him in my corner- he is compassionate in his care of his patients & demonstrates a genuine interest in you as a patient & as a person. There is no waiting when you have an appointment-I literally am called in seconds after sitting down. Hi staff is amazing - Pam, Sarah, and Chloe. Also, when I needed an iron infusion, the crew in the infusion room were amazing. His nurse, Chasity, is so welcoming & friendly. he is an amazing doctor!!!

Dr. Seymour has taken care and control of my affliction for the last 5 years. He is proactive, honest, straightforward and compassionate. As well as at the forefront of new treatments and technologies. His staff is amazing also, Pam at the front and Lauren and crew in the infusion center or all at the top of their craft

The worst doctor I have ever had the experience of meeting. When we tried to ask a question about my husband's cancer care, he asked us if we were going to talk over him. He is very egotistical, and very uncaring. Would not shake my husband's hand when we left because he was afraid my husband would hurt it. Really? This is Texas, ya'll. He's not a surgeon. The ONLY friendly person in the office was the lady who did the blood pressure, weight, etc. The office staff were playing on cell phones

If you don't have good insurance, don't bother going to him, his bedside manner sucked, and he don't tell you the truth, in my opinion he's in it for the money. My brother suffered because his untruth. Shook his hand said good luck. Nice!

He is the worst Doctor that I have ever encountered. I was shocked by his rudeness and his refusal to even go over my test results with me. I am actually checking into this. There must be some legalities involved when I Doctor, who has already been paid, refuses to explain your test results.
