"Dr. Gillenwater is very caring and straightforward. He takes his time and helps you to understand your diagnosis. He is also very good at well patient check ups. I have been a patient of his for a long time and am very pleased with him as a provider. Would 100% recommend."

"When I first saw Dr. Gillenwater, I gave him 5 stars. He is probably a great person. As my doctor no, his(2) nurses are unbelievably uncaring and hateful. I am on Blood Thinners. Gillenwater "said" we would work together for my health. Sorry, doesn't listen, gets upset when I tell him what my body is doing. (BY the way Gillenwater, I've suffered over a year with painful, distressing AFiB/TACHYCARDIA & just had a painful CRYO ABLATION SURGERY @ ST. LUKE'S & according to a nurse you had NO clue. In my opinion , along with two friends who changed doctors from you to other Drs. @ Liberty Clinic you need to listen. You even blew off my CPTSD Psychologist trying to give you pertinent information. Allegedly, you work WITH and listen to the patient ( teamwork)In my opinion-in reality, NOT SO MUCH. I really needed a good PCP, sad. The Office Manager is AWESOME, she cares and takes care of issues.I had a sinus infection and my nose started bleeding I call, nurse said he said he could see me ...
in 4 weeks! On Blood thinners, REALLY? MY wonderful Pulmonogist treated me that DAY! "

" I am in the process of looking for a new PHP due to the unacceptable conditions I have encountered at Dr. Gillenwater's office. His nurse is anything but helpful and seems primarily interested in keeping you out of the office. Dr. Gillenwater himself is friendly enough but beyond recommending vaccinations and screenings doesn't appear to be inclined to get involved with his patients. Add a 6 month wait to get an appointment and this is NOT what I need from a PHP."

"I am grateful to have found Dr. Gillenwater for my PCP. He and his nurse Amanda have been very helpful with my medical issues. The entire staff are friendly, caring and professional. Dr. Gillenwater listens to my concerns and addresses all my questions. He seems to truly care for his patients and does not rush me in and out. He is the best PCP I have had. I recommend him to anyone looking for a physician who cares for your health. Sheila Barnes"

Data Transparency and Trust: Understanding WebMD Doctor Listings and Reviews

We know that finding the right doctor or provider is important to your health. That’s why we want to ensure you have confidence in the provider profiles and listings you see on WebMD Care. Our provider data is sourced from the physicians themselves as well as publicly available databases. Any doctor or provider who claims their profile by verifying themselves can update their information and provide additional data on their specialties, education, accepted insurances, conditions they treat, and procedures they perform.

All the physician and provider reviews on WebMD Care are provided by users just like you. Knowing these reviews provide insight into how other patients feel about a doctor, we maintain internal policies and protocols to ensure the quality and accuracy of all reviews. Providers are not able to remove or modify reviews on their own. Reviews can only be removed after an internal review by our customer service team.

We value your input and encourage you to reach out to our support team if you encounter any issues.
