They were warm, professional, and truly cared for their patients, and the staff felt like part of a small, caring family practice. Unfortunately, as the practice grew, the staff became less friendly and harder to work with. Things declined rapidly once the Muscos left to form their concierge practice (which costs thousands of dollars per year, per patient). Since then, patient care has suffered greatly. Between my wife and I, we've tried several different providers here, and the experience has been consistently disappointing. The new doctors don't listen, and video appointments have been low-quality and unhelpful. The level of care, attentiveness, and professionalism that once defined this practice is simply gone. I finally switched to a physician at Sutter Health, and the difference has been night and day. My new doctor was thorough, actually listened, and helped me get the treatment I needed. I'm so glad I made the switch--my health truly depended on it. EDITED: If you are considering this office, make sure to look at the reviews for the last couple years.

I accompanied my mother to her appointment with Dr. Rajesh Maheshwari today, and as a medical…read moreprovider myself, I was extremely disappointed and concerned by the interaction I personally witnessed. My mother came to discuss years of widespread pain and concerns about fibromyalgia, hoping to discuss evaluation and treatment options with her PCP. Dr. Rajesh Maheshwari was dismissive and condescending and repeatedly raised his voice while discussing her concerns. He repeatedly told her that fibromyalgia is "no longer a diagnosis," despite fibromyalgia being a recognized clinical diagnosis with established diagnostic criteria. When my mother also mentioned CRPS (complex regional pain syndrome), he appeared confused and unfamiliar with what she was referring to. What bothered me most was the way my mother was spoken to. She is a patient dealing with significant chronic pain who came to a physician she trusted looking for help. Instead, when she attempted to explain her symptoms and concerns, she was interrupted and spoken to in a loud, curt manner. His voice was loud enough that I was concerned others outside the room could hear discussion of her private medical information. Regardless of any disagreement about diagnosis or treatment, he needs to improve his bedside manner and the way he communicates with patients, especially those who are already dealing with chronic pain. The entire encounter lasted less than five minutes. Before coming in, his staff told us over the phone that she could come in to be evaluated for this concern. We spent the time and gas traveling to the appointment only to be told after arriving that this was not something he would diagnose or address. If a provider is unfamiliar with conditions such as fibromyalgia or CRPS or does not know how to manage them, the appropriate response is to further one's medical education, review the current literature, and/or refer the patient to someone with the necessary expertise not dismiss the condition or the patient suffering from it. My mother left upset and disappointed. It was especially ironic to hear that fibromyalgia is supposedly "no longer a diagnosis" while saying this directly in front of a medical provider who has seen patients in clinical practice who have been diagnosed with fibromyalgia recently.

After the procedure I asked if it was ok for him to use his microwave oven at home. I had heard that microwave ovens can interfere with pacemakers. The nurse said that she wasn't sure. She suggested to be on the safe side he can use his microwave, but he should run out of the kitchen after pressing the start button. I was appalled. First off my great uncle was a war hero and lost the use of his legs in Korea in an attempt to rid the world of communism. How is a man who is confined to a wheelchair supposed to cook his hot pocket under these circumstances? Just imagine my poor great uncle Sterling having to wheel himself across the kitchen floor to avoid certain death! Is this how we treat veterans in this country? The only helpful person there was Alicia Cruz. I think she was a nurse. She intervened and suggested cooking the hot pocket in the over or an air fryer as these cooking methods will not interfere with the pacemaker. She also noted that cooking a hot pocket in a conventional oven or an air fryer will make a crispier crust. You are a true saint Alicia! God bless you, and God bless America!!

I had a very disappointing experience during my appointment on April 7th, 2025, with Dr. Andrew…read moreCheung, DO, at 200 Porter Dr, Suite #300, San Ramon, CA. From the moment I arrived, the medical assistant, who is blonde and works under Dr. Cheung, displayed aggressive, uninterested, and dismissive behavior that made me feel uncomfortable and frightened. The medical assistant never introduced herself or informed me that she would be administering a COVID test. Things only worsened during the COVID-19 testing. She simply told me to pull my mask down and said, "This isn't going to be fun." She never once mentioned that she would be doing a COVID test or a throat swab, and she didn't explain what tests would be run or why they were necessary. Her overly aggressive approach caused pain and injury when she inserted the nasal swab too deeply, causing bleeding. The throat swab was similarly forceful and painful. When taking my blood pressure, she failed to perform the procedure properly, inflating the cuff and then quickly removing it without obtaining an accurate reading. She never placed the stethoscope like one does when taking manual blood pressure. She also used the wrong size cuff, and instead of properly taking my blood pressure, getting the correct cuff size and recording the result, she fabricated the reading. The assistant was rude, rushed, and unprofessional, slamming doors behind her and showing no interest in my well-being. When the doctor arrived, he was kind and apologized, but the blood pressure reading issue was never corrected on the discharge form. Later, the doctor said the manager would come into speak with me, but after he left, the blonde medical assistant returned and confronted me in a very intimidating manner, asking, "Do we have a problem?" in a tone that felt confrontational. I was shaken by her approach, and instead of offering a genuine apology, she attempted to justify her rushed behavior, claiming she had to attend to another patient. Her response was dismissive and unprofessional. Her appearance back in the room frightened me, as the doctor had told me the manager would be in, not the medical assistant to confront me about my complaint about her. The practice manager, Vicky, dismissed my complaints, suggesting that I was simply having a "bad day," and minimized my experience, failing to acknowledge the serious issues I raised. The practice manager then seemed to defend the medical assistant as if they were friends, mentioning that the assistant had worked there for 15 years with no complaints, and that she herself was a medical assistant for 40 years. She even explained that she was just in a hurry. To which i replied, "they should not schedule me an appointment if they cant take the time to explain the procedure, or properly take my blood pressure, or even introduce themselves" this is no excuse, and there is no reason to rush. It only takes a few seconds to introduce yourself, and explain a procedure. I guess she was trying to justify there was nothing wrong with how i was treated by saying this? Didn't make sense how that was relevant in the moment, and raises more concerns about her lack of concern over her employees behavior towards a patient, given all of the experience she claims to have. This statement that the blonde medical assistant had no complaints in 15 years is false, as there are multiple reviews online with similar complaints about the same medical assistant, who works under Dr. Cheung, highlighting ongoing issues with her behavior and procedures. What's even more concerning is that this particular medical assistant has received negative reviews going back six years, with several patients complaining about similar mistreatment and her aggressive behaviors. It seems that the practice is not taking these complaints seriously, and the assistant's behavior continues to harm patients. Despite the doctor's kindness, the lack of professionalism from the assistant and the practice manager was disturbing. I was left feeling unheard and disrespected, especially disappointing in an institution like John Muir Health, which has a strong reputation. I sincerely hope the practice takes action to address these issues to prevent future patients from experiencing similar mistreatment. I also believe a reimbursement for this visit is warranted. Crazy to pay for care and then be treated this way. I hope no one else has to experience the mistreatment I received during my visit. People who display such unprofessional and aggressive behavior should not be working in the medical field. I sincerely hope John Muir Health takes this complaint seriously and takes action to ensure better care and professionalism in the future, especially for patients who are unable to advocate for themselves or who feel threatened and scared, as I did, by behavior like this.
