Dr. Phillip Werner is an awesome doctor!

May 23, 2020 11:24 AM

Excellent caring doctor.

May 20, 2020 10:38 AM

The video visit worked well

May 18, 2020 9:34 PM

Thyroid checkup post baby delivery. No blood work has been performed in almost a year, which seems odd. Dr Werner always listens to em, but I sometimes feel like I have to repeat myself every visit and receive different opinions during each appointment.

May 16, 2020 7:53 PM

Always very professional and compassionate. His expertise has taught me to live a better healthy life.

May 16, 2020 7:53 PM

Always good!

May 9, 2020 3:29 PM

He is an excellent doctor. I only wish there were more doctors like him out there. He is VERY thorough. He had written tests for me, however, with the COVID-19 out there he just wanted me to wait a while before I went for the tests.

May 6, 2020 9:13 AM

Dr. Werner is excellent at focusing on the specific problem /issue related to my thyroid and explaining its potential impact on other areas of my health. He is clear, and able to explain things in every day terms that anyone can understand. He also makes you feel part of the appointment, and shows great willingness to listen to your questions and concerns

May 4, 2020 1:33 PM

Dr. Phillip Werner is an exemplary endocrinologist/physician who genuinely cares about ALL aspects of his patients' wellness. He listens and never hurries conversations. He factors patient's perspectives and concerns into the decisions and recommendations he makes/provides. And, he is readily available to offer professional assistance/support, even after office hours. I consider myself blessed to maintain my wellness under the direction, care, and compassion of Dr. Phillip Werner.

April 17, 2020 9:33 AM

This was a tele health visit. It was scheduled before the COVID crisis. Dr. Werner's staff contacted me to arrange it well-ahead and also that morning. He has been my endocrinologist for many years. He is professional, caring & extremely knowledgeable - asking pertinent questions and listening respectfully to my concerns. He is an example of what every doctor should be.

I get on well with Dr. Werner. He seems on top of all aspects of my diabetes care and is regular contact with my primary care physician.

November 18, 2019 1:37 PM

my one concern is the possibility of Dr Werner retiring in the near future. I've seen him for a number of years and don't know if I will feel as comfortable seeing anyone else.

November 18, 2019 1:37 PM

Wish Dr. Werner would continue being my doctor by I know eventually that will change.

November 17, 2019 11:00 PM

when trying to get in to see the physician - the central scheduling department could not help me - someone from the doctors office called me and asked me about the issue and why I needed an appointment. They got me a very quick appointment. The central scheduling department is not, nor will they ever be able to replace the excellent staff at Dr Werners office.

November 17, 2019 11:00 PM

get rid of central scheduling - it is too impersonal and very frustrating to schedule with. Dr Werner and his staff are wonderful.

November 12, 2019 11:00 PM

November 5, 2019 11:00 PM

I have been seeing Dr. Werner for over 20 years for my diabetes and thyroid condition. He has always been extremely respectful, interested in everything I had to say. Could you clone him, perhaps? He is a very dedicated doctor and an asset to your hospital!
