From the time Dr O’Sullivan first came to Kaiser and took me on as one of his patient, I.could not be more satisfied and grateful for the care I have received. He is very interested and compassionate about my concern and issues. He is a superb diagnostician and more than once he was able to get to the heart of my problems (which were many over the years)in a very timely manner. When needed, he always sent me to specialists who were equally talented.I am certain I would not be here today if not for Dr O’SUllivan.

Great wellness visit. Took the time to explain options, easy to talk with. The entire operation at the Arapahoe Kaiser in Centennial is easy to navigate, well organized and efficient. Staff are always friendly.

Excellent care
