About
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.

As always, Dr. Sun is open, responsive and calm. It was a ‘well woman check, and he read the file quickly and asked pertinent questions about items we discussed. I came to a turning point this year and discussed it with him and he was very practical and supportive in his responses. I came to ask questions, check in and find out about certain issues, and came away calm, with info I needed to make decisions. Most importantly, I felt listened to. Very important in medicine.

I dont always have enough time. I dont feel heard with my concerns due to rush rush rush. My annual physical was brief. No eye exam, no diabetic foot test especially cuz my colonoscopy was canceled due to high sugars. A yearly physical used consist of so much more, even EKG's. Labs didn't get done due to late appt. Perhaps labs first in this case???Now I must make an appt again for a month out or so. Super discouraged with Healthcare now a days. The staff has always been above and beyond and are why I stay.

Worst Dr’s visit I have ever had. She was rude, condescending, talked too much about issues unrelated to my visit, and refused to offer any medications to alleviate my symptoms (on Thanksgiving day after I left my family and waited at urgent care for hours). She seemed more concerned about her documentation and her license which she referenced that she wanted to “protect”. Very bizarre encounter. I left the visit and got treated like a real live patient at a different urgent care.
