Exceptional in her field, amazing bedside manner is just a few words to describe Dr. Sierra. Dr. Sierra is extremely thorough, listens, and takes interest in finding the root cause of the problem to properly diagnose and treat. She is also a big advocate of sharing as much information as possible with you to learn about your diagnoses and treatment. Aside from the Dr. the entire office staff is friendly, polite, and diligent in returning calls and following up. I would highly recommend Dr. Sierra.

I am a Nurse for 33 yrs and have worked with many physicians. I was privileged to have worked closely with Dr Sierra as well as having her as my personal physician. She is by far the most knowledgeable physician I have know, along with her outstanding commitment to her patients. She is dedicated to their well being and is always available to them. She is a true asset to the Medical Profession.

I have gone to Dr. Sierra. I also went to her predecessor, Joseph Greenberg, M.D. I find her to be very helpful with explaining how metabolism and weight loss work. I recommend her enthusiastically and without reservation.

I owe my life to Dr. Sierra. I was morbidly obese with a fatty liver and on the cusp of developing diabetes. She offered me several options on how to address the issue and helped me through it all. I am in the right weight class my bloodwork is normal and I feel great. I am still following her program and could not be happier. Sheis the greatest and if you are looking for a caring and brilliant doctor you should go to her.
