When I was called back I was asked to give a urine sample. I informed the person who asked that I hadn't menstruated for over 7 years but she still insisted. I was shocked and refused. The woman (she didn't tell me her name or position and did not wear a name tag) then took my blood pressure as she asked me questions, did not offer a way to raise my arm ( using a table or holding my arm up). The reading was way off my typical numbers and I asked her to redo the testing. She said "no it's fine," and refused to redo it. The lady then started walking out and didn't give me further directions. I asked if I should put on the medical robe that was left on the table and she said yes. She was curt, rude and not professional. The bathroom and pre- procedure room were dirty and deteriorated. I saw dirt on the ground and on the walls. I was not properly introduced to any of the staff members whose was shocking. None of them wore name tags! I didn't know if I was talking to a nurse, tech, or doctor. When I was brought to the procedure room, nobody even turned around to acknowledge I was in the room, no less say hi or introduce themselves. A man walked up and said "enjoy your nap" and began to put (what I expected to be) a sedative. I have no idea what his position was, again because no name tag or introduction. I asked what he was giving me because he did not tell me. This was appalling. Also, nobody checked my name tag, asked to confirm what procedure I was having, or asked who I was when I came in. Overall, the surgery center was unprofessional, unsanitary, and unacceptable. If you are reading this before having a procedure, I urge you to go somewhere else.

If you are reading this, I highly recommend to you, DO NOT go to this place. I had a procedure…read morehere on Friday 6/20/2025 and I wish I read the reviews ahead of time (and I will own half of that responsibility). The prep room is the dirtiest I have ever seen at a medical facility. One of the medical techs (or nurse) asked me to take off all my clothes and I was asked to sit on an old blue reclining chair that did not appear sterile with only a gown exposed where my rear is exposed to this old reclining chair. I was barefoot on this dirty floor and the medical tech/nurse reluctantly gave me disposable booties I asked for more than once. She then disappeared never to see her again. After waiting in this chair for around 45 minutes, I was then asked by the anesthesiologist to walk to the operating table, which I struggled to get on. Then I was knocked out with the anesthesia. The procedure was complete and I don't remember much other than feeling rushed to my ride to take me home. When I got home, I noticed I had these red bumps all over my forehead and under my eyes. I made a point to clean myself as much as I can. These red bumps got worse over the weekend and by Monday 6/23/2025 I had a 102 degree fever and nasty cough with phlegm. I called my doctor and he prescribed antibiotics. By Tuesday 6/24/2025 I started to feel an itchy/burning sensation all over my nose and lips. I found out that these are cold sores all over my face (something I have not experienced before). I suspect I got these from the recliner or the pillow in the operating room (that appeared reused). I consulted with my primary care doctor and prescribed Acyclovir. The lack of sanitation and lack of competent medical techs/nurses that were too busy gossiping about their other coworkers (yes, I and other patients heard everything in the prep room) will eventually cause someone serious injury (or worse) some day. It is just a matter of time unless this facility get their act together (I have my doubts this will happen based on the other reviews I read). Please, DO NOT go here (Premier Surgery Center in Concord). Do your research, read the other reviews and do your due diligence (something I did not due). I recommend having your surgical procedure at a hospital where they appear to still have some rules in safety and sanitation/sterile environments.

For a long time, I wasn't feeling like myself -- constant sadness, low energy, painful periods, and so many other symptoms that were affecting my quality of life. My doctor at Kaiser suggested it was depression, but something inside me kept telling me there was more to it. I started doing my own research and learned about Hormone Replacement Therapy (HRT). I didn't know MSPA offered it until they sent me an invitation last October. I made an appointment right away. From the very first visit, the staff made me feel heard and comfortable. They were kind, patient, and took the time to walk me through everything -- what the treatment involved, what to expect, and why it might help. They sent me to Quest Diagnostics for bloodwork to check my hormone levels, and after reviewing the results, we moved forward with the procedure. It was quick -- about 10 minutes -- and the only discomfort was a brief sting from the anesthesia. Within the first month, I noticed a remarkable difference. For the first time in my life, I had my period with NO cramps. I felt happy -- genuinely happy. It's hard to describe, but it's like I finally wanted to live again. Six months in, and there is no going back. This has been a life-changing experience. It turns out it wasn't depression or me "feeling crazy" -- it was my hormones. I would also like to extend my heartfelt gratitude to the incredible staff -- Stacey, Brittany, and Hailey -- as well as the friendly and welcoming team at the front desk. You are all truly appreciated -- every single one of you. From the moment I walked in, you made me feel welcome, cared for, and never rushed. Your warmth and professionalism made a huge difference in my experience, and I am truly grateful for each of you. I can't recommend this team enough.

All the staff were so kind, loving, understanding, patient I can go on and on but it would take me a year to finish this. My surgery went really well but the one thing that really stood out for me was how Dr. Eric Mariotti is not only a good surgeon but a kind, compassionate human being. Even though he has a lot of patients, he makes time for them. I did not feel like a number, I felt the love and the compassion. He had a family emergency that came up and had to leave quickly. When I woke up Friday morning, my blood pressure dropped dangerously low. All the nurses that took care of me,sorry that I forgot your names but you know who you are and you guys were also amazing, loving, kind, and compassionate. I want to let Dr. Mariotti know that you guys were my angels. They called Dr. Mariotti wit their concerns out of his busy life and the family emergency that was going on he came to see me and to evaluate the situation..It does not stop here at all. He also had another doctor to check on me. He called me Friday night to see how I was doing. I have never experienced having a doctor or surgeon like Dr. Eric Mariotti thank you so much for everything you and your staff did for me. I am looking forward in seeing you tomorrow as well as working with you in the near future. I highly recommend Dr. Eric Mariotti

I saw Dr. Diane Kwan in June 2025 for a suspected hernia above my belly button. She diagnosed an…read moreumbilical hernia and confirmed it with an ultrasound, which clearly identified the hernia in the exact area where I had pain and a visible bulge. She performed surgery in October 2025, but I received no post-op communication from Dr. Kwan. I had to proactively call with concerns when the bulge remained. At my follow-up, the issue was still present, and a CT scan later confirmed the hernia had not been repaired. Dr. Kwan then admitted she had repaired a different hernia during surgery and missed the one that was originally diagnosed and causing my symptoms. I was never informed before or after surgery that the correct hernia had not been addressed or that a new/different one was present. I only learned this weeks later after raising concerns myself. This experience was extremely concerning and disappointing, both in terms of the surgical error, lack of communication, and now the need for repeat surgery.

What sets Dr. Kwan apart is not only her superior surgical skill but also her genuine kindness, rare in today's healthcare. She consistently encourages, especially when I'm overly critical of myself for not meeting my self-assessed goals. The impact extends far beyond physical changes. My quality of life has improved dramatically, and I remain forever grateful to Dr. Kwan and her team for being such a positive part of my health journey. Thank you, Dr. Kwan!

He recommended another specialist in the building and even walked down with me to go see them. He kept saying "I'm very honest, not trying to be rude..." which I never felt at all - tell people what they need to know, not what they want to hear.
