Dr. Sullivan is amazing and has been the reason I have been able to recover after 7 years of autoimmune disease and the recent heart attack. I don't know what I would have done without her. WE have been able to work together to come up with a plan. She is found the vital 2 last HUGE puzzle pieces that solved the major neurological issues.

If patient logs in to MyChart and waits in portal for their video visit, the MyChart system then times out the patient causing the patient to be unable to connect once the provider is online! I had to go back and log back in and wasted precious time of my video visit in doing so. This was indeed very frustrating for both me and Dr. Sullivan!

Reviewed on Feb 23, 2021

Once we were finally connected Dr. Sullivan was very attentive. She graciously took a portion of her lunch time to complete my virtual appointment. I felt awful that this happened because the MyChart system timed me out and I had figure out how to reconnect. Please change the MyChart system to not timeout when a video visit is scheduled.

Dr. Sullivan treats me with care and interest in finding the needs of my body. I recommend her highly.

Reviewed on Jan 26, 2021

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.

I really appreciate Dr.Sullivan sharing with me websites in which, as a caregiver, I could get a better price on my supplements. Part of the struggle with keeping up with my supplements in the past is the expense. I have never been instructed to look into these sites, and found myself with a much better priced cart of supplements I needed! Thank you so much!

Dr. Sullivan is a prime example of why your Functional Medicine program will lead the way of health in the future. I can't thank her and her colleges for looking for the root cause of my disease.

This program leads the way. Thank you.
