Dr Sullivan was a lifesaver. I initially saw a different doctor in the Functional Med. Clinic but once my test results were in I was told she didn't have any appointments for the rest of the year. Dr. Sullivan came to the rescue. While it's good for you guys to keep reeling in patients to make your FM clinic a success, it's concerning to patients who can't get their results after thousands of dollars in tests.

Dr Sullivan is familiar with a wide range of possible causes of illness, and helps us understand pros and cons of methods of diagnosis, treatments, side effects, and likelihood of success, either short or long term. She shows personal concern for how my life is affected, and brings an attitude of optimism and humor even in tough situations. She is always seeking to improve things rather than settling for my doing some better but not great; that has led to further diagnosis and help where other doctors had quit.
