Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Highly skilled, compassionate and professional!
Dr. Willis was very thorough, explained everything and answered all my questions. He is very professional, but still very personable.

Dr. Willis and his staff treated me with the highest regard and compassion during a difficult time. I was treated with compassion and respect while including my husband in all aspects of my care and knowledge about my procedure. I appreciated the time he and his staff took with the support of my case before , during and after my procedure. His skills as a surgeon and bed side manner greatly helped me through this difficult time. I highly recommend him and his staff to anyone who is seeking a caring and compassionate doctor.

My highest possible rating for Dr Willis is not based on a few qualities such as knowledgeable, personal, experienced, etc. The best doctors need to have it all when you are counting on them to do everything right during cancer, surgery, chemo and after that. After five years plus of seeing him during that experience, I can say that I have not had a single doubt that I was being treated by the best. It is likely that every five star rating here is from someone who feels the same confidence as I. Dr Willis'staff was also a very important part of my well-being and healthy attitude. I am very greatful.

Dr. Willis is one of the very best doctors I've ever had. I had a pretty complicated case and was referred to him by another doctor who practices in a different field of expertise. It turned out that I would be needing 3 different surgeons working on me for various reasons. He took his time to really listen, examine, and explain to my husband and I what would need to happen. He was the one who became the lead doctor/surgeon, who got the ball rolling for my surgery that finally got me on the road to full recovery after many long months of pain. I cannot say enough good things about him or his staff. You know you are genuinely cared for by everyone there. I absolutely 100% trust him and will recommend him. I'm so thankful I was a patient of his!

Dr. Willis embodies the utmost in expertise, surgical skill, professional care, communication skills, and human kindness and compassion. I have never met a more qualified physician with such a fully encompassing combination of quality attributes. I trust him implicitly, and believe him to be a world class physician and human being. I will be forever grateful to Dr. Willis, and to the doctor who referred me to him.

Dr Willis was an amazing doctor! His positive approach brought me much relief in a stressful time. He skillfully removed a 2 1/2 lb fibroid from my uterus. I would recommend him to anyone!

He performed a laparoscopic total hysterectomy for me. You couldn't meet a nicer Dr. I had no pain whatsoever. The entire staff is very professional and equally nice. Dr. Willis is a Dr I highly recommend. The entire process was easy, met him Monday, Friday was surgery. He had great bedside manner. He explained in detail to my husband and I my problem. Then operated. I've had dental visits that were way worse.
