About Me

Hasaney Sin, MD, studied medicine at Ross University School of Medicine in Portsmouth, Dominica. Dr. Sin chose a career in medicine because he enjoys helping people in any way possible. He specifically chose a career in family medicine because he enjoys caring for the whole person, spending time to get to know his patients, and seeing his patients respond positively to treatments or therapies he may provide.

I want my patients to know that I will do everything I can to help or direct them to the best person to receive the highest quality of care as possible.

Dr. Sin was born and raised in Long Beach. Outside of medicine, he is a huge fan of the Los Angeles Dodgers and enjoys spending time with his fiancé and family, being outdoors, and going camping.
