I'd heard nothing but raves about Dr. Kellar from other medical pros and friends who are his patients. Everyone is sweet and cheerful when I arrive. Dr. Kellar actually listened, took my symptoms seriously, and upon the tough diagnosis, wasted no time in hitting it hard to get me well and out of his hair. He truly cares and that's rare in my experience.

Dr Keller always listens and takes the time as if you are his only patient that day. He is approachable and helps educate you on each visit. I feel confident that he always is ensuring all details are covered. He has been the only doctor that has been consistent with my care during and after my pulmonary embolisms.

I don't know what I'd do without Dr Keller and Amanda Law. They understand what it is like to have an emergency and have trouble breathing. They are awesome. Also, thanks to Jen who always takes care of my Rx and takes good care of me too.

Dr. Kellar is a multitalented doc. He always explains what's going on and gets down to business. And he's an Army Veteran (big plus to me).
