She was so rude she even hung up the phone on me telling me "she wouldn't deal with it anymore" she has no professional manners over the phone doesn't let you speak and refuses to help gets into personal issues instead of focusing on her job. I totally will have to see a different surgeon after this. The worse experience I've ever had when dealing with my health. She is not compassionate at all or even had the skills to speak to you on the phone even after you are explaining your health situation to her. Needing surgery is not a game lady!!! Super upset with this treatment I received from her and for sure won't recommend anyone there.

For years I've gone back and forth to other specialists for my issues with severe stomach pain…read more I've been poked and prodded, done dozens of blood tests, tried new diets, and nothing was being solved. I was just left with bills, questions, and specialists scratching their heads. Finally a friend and co-worker recommend I visit Dr. Nastaskin who practices out of Santa Maria. The first visit he narrowed down the issue, recommend some medication and got me started on it right away. No more needles, no more unanswered questions. It's been three months and I've been doing better now than I have for the last 10+ years. This doctor knows what he's doing, and he doesn't waste time. I can't recommend a better Dr. for anyone suffering a gastrointestinal issue!

I was really freaked out about getting an endoscopy due to another doctor from this practice…read moresending me home for "not following" the approved liquid diet (I did follow it) and that I should have been and be fasting (I was not told to fast). It was very traumatic to say the least. I asked to switched doctors and reschedule and was told Nastaskin was awesome. Well let me just say he is! He has a very calming presence and he made me feel very comfortable. Annie was the anesthesiologist and she was so sweet. Nurse Lana was very gentle and attentive and I really appreciated how well I was treated for this procedure. If you can, go with Nastaskin at this practice he's awesome.

Re: Dr. Joseph Centeno; Surgical Specialists Inc.:…read more When I had to have a "corrective abdominal surgical procedure," I was sent to Dr. Joseph Centeno. Dr. Centeno was "quite competent at his medical specialty" but also patient; a considerate listener and explainer of the procedure to be performed; answering any and all questions that I had. Dr. Centeno is blessed with a "calming demeanor of quiet strength" which really came in handy as the "head of my surgical team" so I always had the feeling of assurance that "under Dr. Centeno" - everything was "alright and under control."

Because a previous operation went terribly wrong and left me permanently disabled, I explained to both nurse practitioners that I now experience significant fear and PTSD surrounding surgery. Whereas the first NP (not at SMG, at a different practice) was cold and dismissive, Sari was entirely different. She listened, asked thoughtful and focused questions, showed genuine compassion, and helped me understand how to advocate for myself with the anesthesiologist. She made me feel heard, respected, and far less afraid. After everything I have endured, finding Sari and Santa Maria Gastroenterology felt like a blessing. She advocated for me, restored my trust, and made me feel seen. Sari is an angel.

He ran test and then he found out that she had cancer so they removed her uterus and then she was hospitalized a few days for that went home and then She started bleeding we didnt know from where we went go to the emergency severAl more times AND KEEP IN MIND DR. TAMMELA TOLD HER SHE WAS CANCER FREE AND SHE WAS SO HAPPY SHE CRIED!! Her granddaughter cried and her son was happy her great grandkids were happy. JUST TO BE BRUTALLY LET DOWN A COUPLE MONTHS LATER after they did the removal of the uterus and then she kept bleeding and then it was at the ER that a bunch of specialist came and looked at her and saw her and I asked them could it be cancer and the young doctor that was there said yes they were afraid the cancer occupied the urethra and the bladder And she ended up dying about three months later. The emotional distress my grandma and family suffered due to the half ass job everyone did was EXTREMELY UNACCEPTABLE and now we have to live with the regret we have trusting these drs my grandma was assigned while they live on and make crucial mistakes on other people , about three months after cancer made itself known again ( I would say came back but it never left )she was in the emergency room and Marian Hospital too couldn't tell the difference between infection, cancer and strokes, and I was begging them for an MRI to see if she was having strokes because she became unresponsive for about three days when I finally saw the doctor again and he said no, it's just a sign of the infection Don't worry about it towards the end when she was not waking up not opening her eyes talking moving anything They finally did a CT scan or MRI and said that she's had about 15 strokes and then we had to make her comfortable and she died. I would recommend going to a different city with different specialists or different doctors to deal with any type of cancer or disease because unfortunately, both my grandparents died over there for things that could've been prevented. Should they have been in a different city. We understand that cancer has a mind of its own but the neglect she received and preventative measures and tests or double checking she didn't recieve is unacceptable so if you want to go through this or put your loved ones through this GO AHEAD!

I wish there was a better alternative.

I had thoracic lung surgery for a case of Empyema back in 2023. Dr Canvasser performed the surgery…read more He should stick to heart surgery. He radically invaded my pleural cavity using a chest spreader breaking 3 ribs, and didn't evacuate all the bacterial infected fluid. There was NO pain management addressed after I was released, as well as NO proper antibiotic management (He prescribed a Z-Pack!!) So, recovering back in Las Vegas, the bacterial infection came back! (Shocker!) and I luckily had a strong and reputable team here at Dignity Hospital perform the surgery with robotic arms, and they flushed the area properly, which should have been done by Canvasser! Also, the team kept me on a 30-day, PICC line IV administered powerful antibiotic to assure the bacteria was eliminated. Wow... I could have died, if left alone and not treated again. Shame on the surgeon, shame on the lack of attention to getting the proper antibiotics administered and releasing me without a plan of follow up. Wow!
