Park Avenue Endocrinology

Welcome to Park Avenue Endocrinology–a leading private endocrinology office dedicated to providing comprehensive and compassionate care for all endocrine-related health concerns. Our team of experienced endocrinologists and in house dietitian/diabetes educator is committed to diagnosing, treating, and managing a wide range of endocrine disorders to help you achieve optimal health and well-being. The physicians all have MD degrees and are Board Certified Endocrinologists from the top fellowship programs in the United States. Each doctor has at least a decade of experience. We believe that personalized preventive care is of utmost importance in helping people achieve their health goals

We specialize in the treatment of thyroid conditions, polycystic ovarian syndrome, bone disease, pituitary, adrenal disease, menopause, and diabetes. Since a successful treatment plan starts with a proper diagnosis we offer in-office testing, which includes state-of-the-art technology such as instant results on thyroid ultrasound, Sudomotor function/neuropathy testing, autonomic nervous system monitoring to diagnose dysautonomia and POTS, and body composition analyzer, basal metabolic rate testing, and continuous glucose monitoring.

Our devotion to good health is the basis and primary focus of our practice is to look at the whole patient as an individual and not just lab levels.

While we use an evidence-based approach having been trained in traditional academic medical schools, we are open to holistic medicine and are happy to work with your holistic provider to coordinate a focus on preventive medicine and longevity.

 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!

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. 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.
