I regret switching to this practice. I've been seeing Dr. Sullivan for just over a year now and I'm more and more disappointed each time I have to deal with anyone from this practice. Referrals don't get submitted, prescriptions don't get sent to the pharmacy, phone calls don't get returned, and messages never get relayed correctly. His approach isn't conventional - he's never checked my ears, nose, throat, etc.; he did labs once to check the basic things but results were never sent to me - I had to get them from the lab's website. I had an ER visit last year and was told to follow up with my PCP but before I could even make an appontment, the office called me and said not to make an appointment but to return to the ER if I had additional issues. Dr. Sullivan seems more interested the DO thing, so if that's what you need, you'll probably be OK......although the last time he did a manipulation on me for back spasms, I couldn't stand up straight for almost 8 weeks and he had left for military deployment. When I recently made a comment about having to be referred out to several specialists, he told me my health issues were too complicated. Perhaps I should have chosen someone with more experience. But I don't think Osteoporosis is too complicated for a PCP to address and I don't think I need to spend the time and money seeing a specialist for it! Honestly, I think 1 star is too high of a rating based on my experiences here.. read more
