Dr. Nassar was extremely helpful and put me on my way to resolve my issues very quickly, I would be happy to come here again if anything arises (but hopefully not haha). She was very professional, kind and a great communicator. ”

She said she cannot help me but she would transfer me to her colleague in her office and that I wasnt a new patient because i was a patient of the practice.. they gave me an appointment and then she said it was cancelled because the other doctor didnt want new patients.. then the practice said I didnt show up to the appointment that they told me I didnt have! Horrible experience

Dr. Nasser was respectful, kind, and efficient without being rushed. Her high level of expertise was evident as she discussed my diagnoses and the reasons why a certain condition can be misdiagnosed. I appreciated that she discussed with me which lab tests to order and why. Overall, highly recommended!

I came in for a hormonal consultation and was happily surprised that I was also able to get a blood panel done the same day. I have a busy schedule so it’s always amazing when I can get the work I would like done same day vs taking multiple days off of work for appointments. The nurses were all very nice and attentive. Dr. Nassar was phenomenal and I plan to keep her as my primary endocrinologist for the future.
October 28, 2024Nadja M.Verified patient
Dr. Rawan was extremely kind and welcoming. I’ve been to other endocrinologists that have dismissed some of my concerns but Dr. Rawan took all my concerns and questions into account and explained everything thoroughly.

It was quick easy

As a first time patient, my online appointment was better than any in person appointment I’ve had with a doctor in a long time. Although the meeting was short, it was a very informative session, and the doctor’s follow up was very thorough.

Dr Nassar took so much time to listen to me and get my full background. I’ve never had a doctor sit with me for as long as she did. She is extremely diligent and trustworthy!
