Thankfully that side was still fine (out of pocket cost $416). Scheduled what I believed to be my yearly mammogram Feb 2026 but they apparentally wanted to bill this as a 3rd FOLLOW UP. This "follow up" however was for both sides and was no different than any other standard mammogram I have ever had except this one costs more than $500 out of pocket. Therefore, this yearly was not covered. So all told a suspicious finding that has now been checked 3 times cost me more than $1500 out of pocket. Lesson learned. Questions the number of endless billable follow ups, especially when they are the exact same as standard mammogram.

Now that Charles River Medical is in the news for harboring a rapist as one of their participating…read moredoctors, I would like to add my experiences. I went there for years not realizing that there are other options in the area to get my medical care. I have had experiences with several doctors there for over a period of years. Their medical care should be reported to the National Medical Review Board for minimal and haphazard medical care. You will be seen for exactly 10 minutes. The doctors will be brief in answering your questions, they will become curt and frustrated if you ask more than 5 questions. They do blood work, go over results, omitting info and if your medical issues are too detailed, you will be sent on your way. I have always left feeling ignored and disrespected, Their Endocrinologist on Union Ave is especially guilty of this. They will not allow you to change your PCP either! Out of sheer frustration I changed to another medical group. I am now receiving minimal one-hour visits with their PCP and Specialists all doctors take great care of you. They do not skimp or cut corners in their medical care, and I feel very well taken care of. Charles River Medical needs vast improvement in their care, their attitude, and their medical expertise.

I was impressed with my primary care doctor, the nurses and the assistants. I felt confident that…read moremy care was being managed. It was fine while I had a commercial health plan. I'm newly retired and have just started on a Medicare Advantage Plan. Unfortunately, CRMA only takes Tufts Medicare Preferred advantage plan. That's the only one. That stinks. It makes me wonder if they really want to service Medicare patients. I had researched the Medicare Advantage options, and for me the Tufts plan didn't cut it. I am an established patient with several specialists in the Mass General Brigham network. All of them took the Mass General Brigham Medicare Advantage plan. It was only my PCP who did not. Several of my specialists did not take Tufts Medicare Preferred. I was faced with having to find a new PCP and keep all of my specialists, or to keep my PCP and a couple of my specialists. Changing doctors is a royal pain, and getting a first appointment seems to typically take a year. My medical situation is that would not work for me. I had selected my PCP at CRMA, because they are part of the Mass General Brigham network. If they were not, I wouldn't have gone there. One frustration with CRMA was with lab work. Patients at CRMA HAVE to use their office. I once tried to use a Mass General Brigham lab. They cannot see the lab orders from a CRMA doctor. I am guessing that CRMA is trying to keep revenues from lab testing. Just a guess.

Sometimes it's hard to get an MD to listen (obviously they know everything there is to know!), and…read moreKramer, MD is no exception. An added bonus/nice touch is that she doesn't feel the need to talk to her patients over the phone (only speaks to them through her admin!). Her bedside manner (...or lack thereof) is atrocious - very forceful and is only a one-way method of communication. My take away is that she's just another typical type-A, a-hole MD, do yourself a favor and avoid this condescending person. Btw, she loves to force meds on her patients - even though they might be not even in the range (only close) of where you would need the rx. You could safely assume a competent MD would would try reasonable methods (diet, exercise, etc) to address medical issues before demanding your patient take meds, but I guess if the MD knows all - there's no debating the subject! Oh - btw, another little chestnut, she hosts clinical trials - no wonder she's such a HUGE FAN of the prescription pad - go figure! Dr. Kramer, please remember you took a Hippocratic Oath, not a Hypocrite Oath.

There was no apology. Also, no one in the office let me know what was going on. So I had to wait in a small exam room until she finally arrived. Then for my last appointment, after waiting 15 -20 minutes, I asked the staff if the Dr was in the office. They informed she had not arrived yet. So I told them I was not going to wait like I did last time......and I left. Needless to say I'm going to see another Dr..... P.S. It was funny that there is a big notice on the receptionist wall saying there will be a $50 charge if you don't show up for an appointment without at least a 48-hour notice. This is hilarious.

Then you find out later on they just didnt want to do anything nor can give you a reason. Find a provider elsewhere. Laura Sullivan NP and Cody Desouza dont properly take note for your medical care and records. They wasted many years of care for me, I should have left sooner. Find a provider who listens and documents properly so you can have better ease of care when trying to communicate.

I rarely write reviews, but I felt compelled to share this experience because I left my medical…read morevisits feeling deeply disrespected and unhelped. I have also shared this same experience via Google reviews. Similar to another reviewer, I had a very negative experience with Mariah Black, a nurse practitioner in the APCC program. Throughout my visits, I felt I was treated more like a customer being dismissed than a patient seeking medical care. I came in for an existing health condition and requested time off from work to focus on recovery. Rather than discussing my symptoms or collaborating on a treatment plan, my request was denied. I was told that I had "plenty of time" to recover and that I should "find another job" if I was uncomfortable going back to work. I found this comment extremely inappropriate, dismissive, and lacking in empathy. At no point did I feel that my concerns were genuinely listened to or taken seriously. Instead, my attempts to explain how my condition was affecting me were repeatedly being brushed aside in favor of her own assumptions and beliefs. Additionally, I expressed that I had financial concerns and could not afford one of her proposed recovery options. At the time, I was reassured that this was understood and would not be an issue. However, I later discovered in the clinical notes that this was documented very differently. The notes stated that I failed to follow the treatment plan, and this was then used as justification for denying me additional time off from work. This contradiction left me feeling backstabbed and left me feeling misrepresented and betrayed. I have been a patient at the Southborough medical practice my entire life, but will now be looking elsewhere for care. I expected compassion, honesty, and collaboration from medical professionals. All of that was entirely absent here. If you are assigned to Mariah Black, please consider my experience when deciding where to seek care. I would not want anyone else to feel as dismissed and unsupported as I did.
