Dr. Margaret Ryan
Dr. Meg Ryan has been working in private practice endocrinology since 2009. She joined Well by Messer in 2023 after relocating from Philadelphia, where she was in private practice for 13 years and was the head of the Division of Endocrinology at Riddle Memorial Hospital. Dr. Ryan has extensive experience managing obesity, PCOS and the menopausal transition as well as other common endocrine issues including thyroid dysfunction, osteoporosis, diabetes and pituitary disorders. She was included in Castle Connolly’s Top Doctors list for the Philadelphia Metro area from 2013-2024 and has been the recipient of the Castle Connolly Exceptional Woman in Medicine Award since 2020.
Dr. Ryan’s goal is to help people find ways to live better and feel their best. She collaborates with patients to achieve what matters most to patients (which is not necessarily the same as what matters most to physicians). Dr. Ryan is particularly excited to be working in weight management today because of the amazing medical breakthroughs in the field over the past several years.

Get to Know Dr. Margaret Ryan
Why Did You Become a Doctor?
Becoming a doctor was a goal of mine since childhood. My mother was a physician and she provided me an up-close example of how fulfilling a life in medicine could be. It is a profession that allows you to use your intellect and extensive training to help others while also forming deep and long-lasting relationships with your patients.
What Made You Focus on Endocrinology?
Endocrinology is a discipline requiring the understanding of multiple separate but interacting hormonal feedback loops throughout the body. Evaluating endocrine disorders can be thought of as akin to solving logic puzzles (a specialty of mine in my high school Math League days!). An additional draw to endocrinology was the ability to specialize while still keeping the workings of the entire body in mind, because the hormones we study travel through the blood stream to have disparate effects on multiple systems.
What Is Your Approach to Medicine?
I think of myself as basically a highly trained medical consultant. Patients come to me for advice, then decide on their own whether to follow that advice or forge a different path. Thus, part of a physician’s job is to endeavor to be both trustworthy and persuasive, for no one would follow the advice of someone that they did not trust. Similarly, advice given poorly or in an unpleasant manner is less likely to be followed. To prove myself trustworthy, I make sure to stay up to date with the latest medical literature in my field and I aim to provide all information and options available to my patients. To be persuasive, I aim to understand my patient’s point of view, their priorities and their fears, so I can address my medical advice to towards their greatest concerns.
How Would You Define Patient Care?
Patient care includes addressing specific health concerns while never losing sight of the patient as a whole: their quality of life, their preferences, priorities and long-term goals.
Do You Do Any Philanthropic Work?
My family has been involved in multiple education based nonprofits as well as international health charities. More locally we participate in service opportunities through our church and our childrens’ school communities.
