About this clinic
Dr. Bay Private Practice, a functional-medicine clinic in New York, offers individualized consultations for patients with complex chronic conditions including gut dysfunction, autoimmune presentations, hormone imbalances, and thyroid health concerns. The practice combines diagnostic workup with functional-medicine assessment, nutrition counseling, and hormone-replacement therapy to address underlying physiologic imbalances rather than symptom management alone. Treatment plans are tailored to each patient's lab findings and clinical history. The clinic serves both local and remote patients, providing an integrative approach to conditions that often benefit from coordinated hormonal, nutritional, and systemic support.
From my very first appointment, Dr. Bay made me feel truly heard and cared for. She listens closely, asks thoughtful questions, and takes the time to understand the full picture of what I am experiencing. When my health was declining quickly and I felt overwhelmed and discouraged, she did not dismiss my concerns or rush through appointments. Instead, she worked tirelessly to find answers, ordering thorough and appropriate testing and carefully reviewing every detail.
What sets Dr. Bay apart is her ability to explain things in a way that actually makes sense. She took the time to walk me through my results, explain what was happening in my body, and outline a clear plan forward. She provided answers and insight that I had never received from any medical or functional medicine doctors, which was both validating and life-changing.
Because of her care, my symptoms are now manageable, my health has improved, and my overall quality of life is so much better. She is incredibly kind, compassionate, and knowledgeable, and I am deeply grateful for the role she played in helping me regain my health and confidence. I cannot recommend her highly enough.

Finding Dr Bay was the best thing in 2025. She listened to me and came up with an idea of what was going on with me. After texting that confirmed what she suspected I have been on a journey to get my gut micro biome healthy. We are working through the phases she has laid out and with each one I have felt better and noticed other positive changes. Not only is Dr. Bay amazing but Felicia in her office is super responsive and helpful as well. Although they don’t take insurance or provide super bills every penny I have spent has been well worth it to be listened to and to get answers when my symptoms were being dismissed and I was not listened to by my PCP.

Dr Bay has been incredible in helping me with my gut and perimenopausal issues. She did more for me in the first 6 months of visits than anyone I had previously reached out to for help. She is so very knowledgeable and is such a great listener. I highly recommend her services to those of you that feel like you've tried everything and don't know where to turn for answers.

Dr.Bay has been an integral part of restoration to my hormone and gut health. I recommend Dr. Bay without hesitation for her dedication to getting to the root cause of my health issues. She has the knowledge and the tools to help you get balanced and healthy. She listens and guides you with every step. The lifestyle plans for diet and changes are challenging, but ones I needed in order to heal. I cannot thank Dr. Bay enough for helping me feel better than I have in years.

Dr. Bay has seriously changed my life! I feel like a different person since I started seeing her in October 2022. I used to have terrible gut & hormone issues, and through her guidance and support I feel so much better and so in charge of my health. She is extremely knowledgeable and cares so much about her patients. She continues to support me through my journey to feel my best and I could not recommend working with her more!
