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.

It’s always a little worrying going into an appt with a new doctor. Dr. Sin was warm, kind, attentive, and just felt familiar. He should be very proud of his bedside manner and practice. I couldn’t be happier with my luck of having him assigned to me, and actually look forward to seeing him next year.

Susana M.
I first encountered Dr. Sin in Urgent Care. I was impressed by his calm approach, excellent listening skills and willingness to discuss health concerns. When I found he was on staff, and available as Primary Care, I made an appointment. I’m also impressed by what seems to be an admin decision by Memorial Care, to have the intake person spend more time on the vitals and routine info, allowing the Dr. more time for patient Q&A, which maximizes visit time and for me, confidence in care received. So, definitely a ‘10’ all around!!

Kimberly C.
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.
