5-Star Yelp ReviewNorinne S.
"I wish there were more than 5 stars to rate the awesome quality of care that Dr. Dominguez and his staff provides. My husband and I have been patients of his for over 20 years and not a day goes by that we aren't incredibly grateful to have him as our primary care physician. He takes time to listen and get to know the whole person and as such, he has been able to diagnose symptoms and illnesses that helped us more quickly get the care we needed or get referred to a specialist when required. He cares more than any doctor I've ever met and goes way above and beyond."
