I’ve been a patient of Dr. Willis for almost 10 years and I won’t see any other doctor. He’s very educated, compassionate, good problem solver, and is very understanding and allows the patient to have a say in his/her treatment. He gives you the time you need to explain your situation without feeling rushed or judged. I trust him fully. He’s in it to help people. A very simple man. Just be open and honest. Your a human, not a customer with him. I highly recommend him.

He is very caring and shows expertise in a lot of different areas. My other doctors seem to think very highly of him. He always spends the necessary time with me and all of my questions are answered before I leave. I usually receive a follow-up phone call the next day from his office.

I am so very pleased having found Dr. Willis and having him as my doctor. He never rushes me out the door, and listens very intently to everything I have to say. And, what is really great is that he does NOT overbook his patient base, therefore allowing ample time with each patient. Because of not overbooking the wait time in his office to see him is very short.

Dr. Willis is the best doctor I have ever had or personally known (AND I HAVE A BROTHER IN LAW WHO'S A DOCTOR). HOW WAS HE ONLY RATED 2.5 OVERALL (BEFORE I ENTERED MY OPINION) WHEN HE HAS AN AVERAGE OF 4 STARS FOR EACH QUESTION THAT RELATES TO HIM AS A DOCTOR? More doctors should take the same time and care of their patients as Dr. Willis does.
