Called yesterday regarding extreme shortness of breath and was able to see Dr. Kellar the next day. He always takes the time to review the test results in detail and answer my many questions. He evaluates the big picture of one's health to try to help find the problem even if it doesn't fall in his realm of care which is rare. He truly cares which means a lot to those of us who have dealt with doctors through out our lives with chronic health issues. Thank you Dr. Kellar! You help a person keep fighting to figure out the cause of our issues vs just shrugging your shoulders. Sincerely, Christine P.

You know what makes me mad? Is the fact that I didn't find him sooner! He's the best. So helpful, so knowledgeable, and a literal life saver. Super nice man and the staff is fantastic. You are going to wait a little bit for your appt so bring a book but trust me, it's worth it!

Excellent doctor and staff. My husband Ron was a new patient and was able to get an appointment the very next day after we called. Dr. Kellar was very easy to talk to and explained things well. We didn't feel he was trying to hurry us along.

Doctor Keller and his staff are always extremely professional and friendly. They take their time with their exams, explanations, and always making you feel extremely comfortable with information that has been given to you. I have several specialists that I work with, and the office is great with communicating my progress with the other doctors to ensure that I am receiving the best care from everyone involved.

Dr. Kellar and his staff are knowledgeable, thorough, patient, and kind. From the second you walk in the door until the second you walk out, they take the time to really listen to your concerns, answer all of your questions, and you never feel rushed. I walked out of my appointment feeling confident about my treatment plan and grateful to have finally found a doctor who considers all aspects of care instead of just writing a quick prescription and sending me on my way. I'm so thankful to have found this practice, and highly recommend Dr.Kellar and his staff.
