Lloyd Cassidy

Dr. Lloyd Charles Cassidy, M.A., M.D.

Family Medicine


Physicians serve as “natural attorneys” for patients, helping them to exercise their right to medical care. As a physician, I believe I have “assumed responsibility for a sublime mission” to help patients get the care they need, with as much of it provided at the local level as possible. 

I began studying medicine to help bring about a more equitable distribution of resources, to provide care to those who might not otherwise be able to access it, and to ease the financial burdens associated with health care. I chose to specialize in family medicine because that is the skill set most needed in remote, rural and international settings.

I completed fellowship-level training in high-risk obstetrics, including cesarean delivery, colonoscopy, endoscopy, ultrasound, and other advanced procedures. I have a specialization in HIV medicine, as well as travelers’ health and tropical medicine. I have a special interest in gynecological health and infertility, approached from the perspective of restorative reproductive medicine. I am trained in fertility awareness-based methods of family planning, and am a Certified FertilityCare Medical Consultant. 

Additionally, I have an interest in healthcare ethics and hold a master’s degree in philosophy and a certificate in healthcare ethics.

Spending time with patients is a highlight of this profession, and it’s rewarding to provide them with the care they need

"Dr. Cassidy did a great job helping my wife and I develop a game plan for starting a family. He is the third fertility specialist we have visited since being married 6 years ago and was the first to give us hope and some solid advice and practical solutions. "

Data Transparency and Trust: Understanding WebMD Doctor Listings and Reviews

We know that finding the right doctor or provider is important to your health. That’s why we want to ensure you have confidence in the provider profiles and listings you see on WebMD Care. Our provider data is sourced from the physicians themselves as well as publicly available databases. Any doctor or provider who claims their profile by verifying themselves can update their information and provide additional data on their specialties, education, accepted insurances, conditions they treat, and procedures they perform.

All the physician and provider reviews on WebMD Care are provided by users just like you. Knowing these reviews provide insight into how other patients feel about a doctor, we maintain internal policies and protocols to ensure the quality and accuracy of all reviews. Providers are not able to remove or modify reviews on their own. Reviews can only be removed after an internal review by our customer service team.

We value your input and encourage you to reach out to our support team if you encounter any issues.
