Dr Natalia has really great insight into what I had going on and really listened and took everything into consideration. I’ve tried to see so many doctors who have just dismissed me with basic bloodwork, it was great to see a dr who was willing to actually give me some time!

Today was my first visit to Dr. Viera. From the start, I was treated with care and compassion. Yahini made sure of that because it was her smile that initiated the positive encounter. Dr. Viera listen to what I had to say and provided guidance. Thank you!

She is a very friendly and honest doctor. I was looking for a naturopathic doctor and she was surprised to know that ZocDoc had her listed as one which she is not. But she was knowledgeable and steered me in the right direction to try and get what I was looking for. If you are looking for an endocrinologist I would recommend her.

I had previously had a very bad experience with an endocrinologist and was very nervous. But she calmed all my nerves. She was absolutely lovely and actually listened to me. Not knyk was she great but the nurses were too. Overall a very good experience and would highly recommend her!
