"Dr. Kaiser is a brilliant, compassionate doctor. He listens to every word I say, asks important questions, & keeps investigating the problem until it is solved. He is calm, confident, and quit-witted. Any patient of Dr. Kaiser's considers himself lucky! "

"Hi everyone...hitting 50, I was very nervous about my first colonoscopy...Dr. K from the minute I met him was the MOST RESPECTFUL, THOROUGH, PATIENT, DETAILED, REAL, LISTENING doctor of ANY medical office I ever visited...he treated me like I was his first patient ever and I left feeling so comfortable with what to expect, and he even remembered the smallest things about me 3 months later! His staff, process, bedside manner, and facility were top notch and he explains everything after the procedure...I have never been so impressed...especially on a something that can save your life...he is in this for the patient...not the medical system...I strongly recommend this gem of a man and his expertise! Thanks, Dr, K! "

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.
