“Patty was very friendly and I loved that she asked me a few personal questions, she wasn’t just a robot trying to check boxes. Dr Sarmiento was very thorough and kind. I appreciate that she dug a little deeper and I didn’t have to ask too many questions to get to the bottom of things, this is a Dr who does her job well.”

We’ve been looking for a Dr like Dr. Sarmiento for forever. Her and Nurse Patty make a wonderful team. Dr. Sarmiento took the time to ensure all of my questions were answered and she thoroughly examined my 18 month old. We hope we found her forever Dr!!

Dr Marta was great and caring. She explained everything clearly. The wait time was okay! We actually hope it would be faster next time
Our visit with Dr. Marta Sarmiento went very good. We struggled to find a good pediatrician for 2 years for my 2 1/2 old son, and I think we found one! She answered all our questions with full detail which we appreciate. The staff was very friendly and not to mention they have a wooden bead maze and television in every room to keep your child entertained!

Staff is friendly & welcoming. Dr. S. is very personable, deeply cares for her patients & their well being. My 16 year old son feels very comfortable discussing his health & never hesitates to ask questions. She provides time we need to talk & we never feel rushed. Saturday appointments are a plus, allowing my son not to miss school!
Loved Dr. Sarmiento from our very first visit 15 years ago! She takes time to listen to and address all of our concerns. Her staff is awesome! The office is kid friendly, Disney Movies and wallpaper balloons and lollipops. All four of my children love to come in. We don't mind the wait because we know she gives all her patients the same attention she given us! Worth it!
Excellent... as usual!! Dr. Sarmiento really knows what to do- her expertise is unmatched. Been coming here for 10 years for all my four children. We love you Dr. Sarmiento and her wonderful staff. Thank you for all your hard work!! :)
We love Dr. Sarmiento! We are satisfied w/ her care. The staff is amazing and very kind. The office is always very clean as well. Overall Dr. Sarmiento is the only pediatrion I completely trust for my kiddos.
My visits are ALWAYS pleasant. The office staff are professional & friendly. Dr. Sarmiento is friendly and extremely compassionate. She explains everything and has such a awesome connection with her patients. I can honestly say my son would'nt be alive if it wasnt for Dr. Sarmiento. She offers state of the art medicine and is so knowledgable in Pediactrics. She has more then once kept my son out of the hospital because of her plan of action for my son's chronic medical conditions.
