I’m not sure who else is at this practice, but I only go there to see Dr. Clifton Jackness, the best Endocrinologist EVER! I’ve been with him for a few years now, and he has helped me so much with my borderline diabetes, along with my hair-loss issues and more. What is special about him is that he really listens and sees you holistically, then takes everything into consideration for the correct prescriptions and immediate feedback after lab work. He is very thorough and cautious. I would highly recommend him wholeheartedly! And he is the nicest person to boot! A wonderful doctor with great bedside manners, which is rare!

Doctor Goddard is an amazing physician. She displays excellent bedside manner and support staff is amazing. They no longer take my insurance but I’m learning you get what you pay for. I will be back soon even if I have to pay upfront and submit to insurance. Thank you Dr. Goddard!!

I have been going here for about 10 years, four times a year I see Dr. Eytan. She’s great and a really comprehensive physician. I feel my visit are through and clear. She’s easy to communicate with in the portal. I find the office staff and nurse to be pleasant.
