He is an amazing doctor! He takes the time to listen to your issues (both medical and personal) and is very attentive to your care. I've been seeing him since I was 10-years-old (I'm almost 30 now) and he's always had my best interest. I highly recommend going to see him if you're looking for a local doctor in Middlesex county!

Bad. Very unprofessional. He was the covering physician for my sister's doctor. I tried to reach him to discuss a serious concern I had with my sister's care at Northwood rehab in Lowell. He had a staff member from that facility call me back to tell me to stop bothering him. She cannot advocate for herself and I am her health care proxy. Very discourteous and uncaring.

The Very Best Ever. I am disappointed to learn that he has moved to Westford because it is very difficult for me to get transportation to the new office. I tell everyone what a great doctor he is but hope he doesn't get so busy he won't have time for me. I am not leaving my name but he says I am going to live to 105, so he will know who I am.

Dr Bertos is great, their admin staff is very difficult to work with along with very poor follow up with admin team. Sue is very difficult, unpleasant and quite rude/impatient on the phone. Calling for an ederly person with late stage cancer Sue was rude, unpleasant and no compassion. Waited 4 days for prescription to be refilled and then they sent it to wrong Pharmacy....ridiculous.
