Luckily I live in walking distance of this location. So I have always mentioned that since I can't/don't drive I can only go to the Thorndike St. location. This week I had a appt there. But when I went to check in was informed that the appt. was for there Pawtucket Blvd. location. And they try to make it that was my fault for not requesting to be seen at Thorndike St. As I have said I have only been to their Thorndike St. location in 5 years and do not drive. There should be some place in my personnel info. that I need to be seen ONLY at Thorndike St.

Does it make sense for a doctor to prescribe a medication that no single pharmacy in the entire…read moretown has? And when you call back to get any sort of help, you get screamed at by the oncall doctor who is unhelpful, and does not understand empathy or pain of patients who have to do so much to advocate for themselves over and over again to get access to SINGLE MEDICATION? I came at 1:45pm to be seen. After 5pm, the prescription finally gets sent out. When it gets sent out, I'm on the phone with over 5+ pharmacies, over and over again who all say they dont have the medication, but they do have the elixir form. I call the oncall doctor (who is not my doctor because I'm running out of time, and pharmacies will close) to see she can send the elixir form and she starts screaming at me saying I shouldn't be using the phone. Rupa Reddy, you're a sick awful severely deranged person. I have had a severe mouth sores for over a week hoping they can help, and now the day is over, everyone left, and I did not receive my medication, and I'm in severe pain. Thats just how awful this office is, they don't give a shit about their patients.

My husband and I recently moved to the area and needed a new primary care physician. I researched…read morethe area and saw Chelmsford Primary Care had great reviews, and that Dr. Sun was accepting new patients. My husband and I got our appointments within 2 weeks of contacting the practice and they were one right after another which made it so easy for us. When we arrived, the women at the front desk were SO kind and helpful, and they truly made us feel at home right away. The medical assistant (she had pink hair) was so friendly and very good at her job. Dr. Sun is easily the best PCP I've ever had, and I knew that right off the bat. Not only is she incredibly warm and kind, but she is thorough, upbeat, understanding and truly listens when you bring up a concern. She made me feel comfortable within seconds of meeting her and I could tell she not only cares deeply about her patients, but she is an excellent doctor. My husband had an equally positive experience with her. We are very happy to have found Chelmsford Primary Care and Dr. Sun, and we hope to be patients here for many years to come.

So as a result, I assumed my blood test report was okay. But when I received my blood test results by mail few weeks later, as I requested so, I was very surprised to find out that my blood cholesterol, LDL, and Trig were SIGNIFICANTLY high, and HDL was SIGNIFICATLY low. I did give call multiple times to the Doctor's office and asked them to inform this issue to the Doctor and so he can advise what should I do. But I never received a phone call. Then I decided to call back again and informed them that I had to change the PCP for such a poor service. It's the question of my health. They told me that they in fact did inform the Doctor. But the Doctor didn't even bother to discuss this serious matter with me! What's the point of regular check-up then!
