    Dr. Beaumont is an excellent doctor. He is always very thorough and takes the time to make sure all of your questions are answered and you understand. He takes care of the whole patient, very rare to find doctors who take the time to do this. He removed my pituitary tumor 3 years ago and I'm healthier than I have ever been. So thankful for him and all his help!!
