What People Say About Tatiana Sadak, NP
The BEST doctor I have ever been to. I worked in the medical field before I retired. Dr. Sadak is cutting edge and is beyond knowledgeable. She knows more about dementia and nutrition than any of my other Doctors. It is hard too schedule with her because we her patients don't want to leave her. She has done so much for me and I really couldn't do without her care. She's amazing.

Very nice and sweet. Hard to schedule appointments as the office isn't open often and when It is, it's on a on a weird, unpredictable schedule which makes planning ahead extremely difficult . We were asked to reschedule several times, which is hard because of office availability.
