In my opinion so far I would not change doctors for my children. Doctor Rivera and her PA are nice and they both explain things well. I miss one of her nurses, because she was always on top of things, but all of her employees are great. I will stay with them until my babies are no longer . Your office does a great job don't ever change. Thank you so my for everything.
