Dr. Bertos was on my plane on my way to Boston. A person in my party had a medical emergency and he stepped up to help. He was extremely helpful and caring, sending lots of thanks from our university group!

Michael Bertos is a knowledgeable doctor and the only reason for 2 stars. His staff however consistently have had communication over the many years I've seen him. I received a text confirming my appointment. I get to the office on the appointment day, we called you earlier this week to cancel. I asked date and time. They gave me the same time I received the text confirming, stating they called twice...I confirmed my number. So I can get confirmation textn but not a cancelation?!?! No apology, just we can give you his next ap... read more

Dr. Bertos has been my PCP for years. He is personable, friendly and explains the diagnosis in simple terms and discusses treatment options. I am so grateful to have found such a great PCP. The only downside is that Dr. Bertos has become so much in demand that it's difficult to get an appointment with him.

Always feel rushed lately. I've been seeing Dr. Bertos for 15 years plus. The last few years, he hasn't been himself. I was just there for my yearly physical and although he still seems caring to a certain point, it also seems that when your time is up, you're done and so is he and he's out of the examining room! So much so that he even forgot to write down some of the blood work he mentioned he wanted to be done but wasn't and now I have to go back again for more bloodwork and maybe fasting once again. Very frustrating.

Dr. Bertos has been my doctor for most of my adult life. I trust him and his staff. They are caring and responsive. Dr. Bertos is up on the latest treatments and he takes a careful clinical approach. 

Business response:

Thank you for the kind review, Bill! We will be sure to share it with Dr. Bertos.

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.
