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. 

Business response:

Thank you for taking the time to leave us feedback. We apologize that your experience with us did not meet your expectations. We would appreciate the opportunity to discuss this with you. Please call our office and ask to speak directly to our Practice Manager.

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. 

Business response:

Thank you for the kind review! We will be sure to share it with Dr. Bertos. Our office location at 20 Research Place is being renovated, so we are temporarily located in Westford. We plan to return to our office location in North Chelmsford as soon as the renovations are complete. Thank you again for your review!

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.

Dr. Bertos is an excellent, through, and knowledgeable doctor. He provides through testing and diagnostics; he also provides discussion, opinions, and options for treatments. He is a doctor that will work with you. He is the best and most trusted doctor that I have ever worked with.
