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.

If someone calls in to request an appointment normally at a doctors office they get your name and birthdate so they can look through your chart as you go on about what is ailing you. She does not do this. She waits for you to tell her your name and birthdate And give her the long dialogue of your ailments then decides "oh maybe I'll should look you up in the system". Then she get your info looks at your chart and reads the notes you just told her about. Normally this would be no big deal but she is not friendly she's not patient. Shows no bedside manner not the kind you need in a doctors office especially a surgeon when you are dealing with people that are in pain or scared of the issues they are facing. Dr maybe some personnel training is in order. Note I am posting this for a patient of yours so that no retaliation from the receptionist will take place to them.

This review is for Sari Winans, N.P…read more I had the unusual opportunity to compare two pre-op consultations at different practices for the same surgery. 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!
