Welcome to East Coast Medical Associates


East Coast Medical Associates Endocrinologists Boca Raton & Delray Beach, FL

Providing concierge quality service without the extra expense

All of our board-certified physicians are on the faculty of the Charles E. Schmidt College of Medicine at Florida Atlantic University. We have extensive experience in managing patients with endocrine problems in an outpatient setting as well as in a hospital. Our compassionate professionals are adept at managing each patient’s problem(s) in a manner consistent with their needs and desires. We work together with patients’ other physicians to deliver comprehensive care of endocrine/metabolic problems. Our doctors are on the staff of Boca Raton Regional Hospital, Delray Community Hospital, and Pinecrest Rehabilitation Hospital, and we were the first Endocrinologist at each institution. We are the oldest and largest Endocrine group in Boca Raton/Delray Beach, practicing continually since 1981.

We have on-site diagnostic facilities with modern equipment to expedite the outpatient process of evaluation and treatment of hormonal/endocrine disorders. We look forward to working closely with you and your physicians.

What patients say About ECMA

We wont let you down, we are here to make you feel good and and recover quickly from any desease you are facing,

  • The staff is helpful and Dr Rodriguez is good and not overbearing.

  • Love this practice, no longer have the frustration of waiting to see my doctor -I love the personalized service! Dr. Frager and staff are wonderful!

  • Dr. Freeman is a superior caring physician who isknowledgable about the field of endocrinology. The follow-up of the office is superior . I highly recommend her.

  • Went in with vague symptoms, knowing I just didn't feel right. He was thorough enough to do plenty of tests to find an answer. Something my internist didn't do. I am glad I took it upon myself to go straight to a specialist.
