I cannot thank you enough for the absolute best medical care I have ever received in my 58 years of…read morelife. From my initial appointment through today, your concern, medical knowledge, expertise and patient care is impeccable. You truly are amazing and care about your patients and it shows by how you have treated me. From my initial appointment, in a matter of weeks you accomplished having my liver biopsy, Lynch Syndrome diagnosis, colonoscopy, pathology report, ct scan and referral to Dr. Yee. You have an amazing gift and I am so glad God chose you to be not only a doctor, but my doctor. I would like Sutter to know what an amazing asset you are to your patients. Your intervention in my life, saved my life, no doubt! I pray God will always shine His face upon you and give you His favor, because doctors that are truly focused on patient centered care, are few and far between and you Dr. Nazareno are one of those rare gems!

I have seen him evolve into a fabulous practitioner for his patients and leader for his department. All his peers and co workers always speak highly of him. That says a lot. Modesto is fortunate to have him.

I don't often write reviews of a clinic but after visiting All Functional Health in Turlock and…read moreworking with Dr Mark and the staff I felt compelled to write a review. I'm so incredibly impressed with his attention to detail and efforts to really get to the root cause of what was wrong. He's careful to take time with each patient and really listen to what is going on. Then he carefully decides the action plan, carefully selects the types of tests he needs to run to identify the root of the problem and utilizes the information to get his patients well from the inside out. You can tell he genuinely cares about his patients and deep down he IS genuinely a good person. So many other GI doctors just want to prescribe their patients a bunch of medications to cover up the problems. Dr Mark really wants to get you better! And the staff is always friendly and helpful. They go above and beyond for their patients and it makes a world of difference! Thank you!!!

We made a functional medicine appointment for her with Dr.Mark and he immediately knew what to recommend for her. This is the first time in 4 years that my mother did not have a bad reaction to new supplements she tried and she actually says that she feels better when she takes them. For my family, this is great because its one step closer to helping her body heal without prescription drugs and this has been a 4 year battle. I just stocked up on supplements for her actually. Its the perfect combination. This place has their own supplement line which is awesome!

I called today at 11:35am from my home in Manteca to schedule my colonoscopy with Doctor Dam since,…read moreshe is in network on my very expensive PPO through Blue Shield. My family pays $39,900 per year in premiums for the privilege to be able to NOT have to get referrals from a primary care doctor as this is NOT an HMO plan. The lady that answered the phone for Doctor Dam was TYLER and she was the least helpful rudest receptionist I have ever dealt with at any doctors office in my 50+ years. This is pathetic and dumbfounding to me that TYLER told me that her office policy from Doctor Dam is that she requires a referral regardless that I have Cadillac PPO insurance. This is not what I am being told by Blue Shield so, I am reporting Doctor Dam to Blue Shield that she is in breach of her contract regarding the service, terms and conditions of her accepting Blue Shield customers and is overriding their policies with her own. Customer NO service is what this is and unsettling to me!

I was impressed with Dr Dam's profile and the fact that she was highly recommended. I got my…read morereferral and waited. I called and was told my request was in review. I called again. Same answer. Then I was told my referral was too vague. I asked my doctor to send a detailed referral. That was done and I waited and waited only to be told that it was in review again. Three different times I was told "they will call you tomorrow". That didn't happen nor have I ever received a call, so good luck people trying to get an appointment. I contacted another doctor, had a referral sent and got an appointment within two days.

Now my second colonoscopy was performed at the Sutter Health Surgery Center in Modesto on July 17, 2024. The Hospital's staff and the wonderful Dr. Vida Chen, a Gastroenterologist are "ALL SUPERIOR / FIVE STARS RATING" members of the medical field!! My wife and I NEVER in our 65 years of existence, ever met such a loving, caring, keen listeners, attentive, accommodating Doctor, or Hospital staff members ever before!! It was like we entered the fictional "Leave It To Beaver" Hospital zone, where EVERYONE is so sweet, and caring, something we NEVER experienced in the Bay Area or at any Peninsula Hospitals! The first 16 oz dose of the Suprep mixture, and the following two 16 oz doses of cold water made me so nausea! The second go around at 4 am the following morning wasn't as bad, and my stomach calmed down by the time I had to head to the Sutter Health Surgery Center. Upon entering the Sutter Health Surgery Center, and engaging with the delightful staff, a calmness flowed over my anxiety. And when the GREAT Dr. Vida Chen came to my bedside to met me, prior to the procedure and patiently had a personal one on one Q&A session with me. I felt SO AT PEACE! Thank you Dr. Vida Chen, and ALL the WONDERFUL STAFF members at the Sutter Health Surgery Center Modesto for making me feel so protected and safe with the procedure!!
