 Trustindex verifies that the original source of the review is Google. Dr. Clifton Jackness is a thorough and compassionate endocrinologist who treats you as a whole person, not just a diagnosis. The practice goes above and beyond in managing multiple medications and navigating the insurance process. Their advocacy and persistence truly set them apart. I am so grateful for their care.

 Trustindex verifies that the original source of the review is Google. Dr. Jackness, Was incredibly kind and really worked hard to figure out what was happening with my daughter. He gave her his personal cell number and was extremely responsive to her questions. When we had to make a return visit he did not charge us. He also took the initiative to consult with her GP and another specialist on her behalf. I can’t recommend him highly enough. Sara Goodman

 Trustindex verifies that the original source of the review is Google. I have been a patient of Dr Goddard since 2013 & I continually travel to see her from out of state as she is the only Endo I’ve ever had listen and look at all my symptoms holistically. Having been diagnosed at 13 with graves she has been able to navigate a healthy IVF pregnancy after being diagnosed with gestational diabetes. I’m so grateful to be a patient of a doctor who really cares!

 Trustindex verifies that the original source of the review is Google. I love Dr. Shira Eytan. I will follow wherever she goes.  I'm a terrible patient but she holds me accountable in a non judgmental way.  She is kind and professional. Update: her office no longer accepts any insurance which is truly disappointing as I now am forced to find a replacement.

 Trustindex verifies that the original source of the review is Google. Dr. Jackness is an exceptional endocrinologist. He takes the time to figure things out. He genuinely cares about outcomes, and consistently goes above and beyond. The staff is friendly, the office is modern and there is never a wait time. Priceless.

 Trustindex verifies that the original source of the review is Google. Dr.Jackness is an outstanding endocrinologist. His expertise is what sets him apart. I always feel heard, supported and truly cared for - in a way that no other doctor has made me feel. He has taken his time to understand what I’m going through so I now feel the best I’ve ever felt. The office staff is always so friendly and I never feel rushed through my appointments. Highly recommend! I’m so grateful to have found Dr. Jackness!

 Trustindex verifies that the original source of the review is Google. I’ve been going to Dr. Gillian Goddard for years now and she is the best doctor I have ever had.  She always listens to me, she is patient, straightforward, and endlessly kind.  Jordana, the nutritionist is also an absolute gem and really helped me understand how to eat well without feeling deprived.  The office staff is so kind and helpful, and the nurses are a dream.  I will never go anywhere else.
