TANYA DAM, DO REVIEWS

Dr. Dam listened to my concerns and answered in a professional way. She asked questions then gave options, we reached testing decisions and she had her assistant schedule the procedure right there and then. I appreciated the service and assistance received. Her assistant Chris was also professional and friendly. Chris was very knowledgeable; having worked in the Professional area of training those looking for jobs, how to dress for success while maintaining a professional image including other areas, I would suggest that he wear proper top/shirt attire to be identified as part of your staff team. Please know that the service was very prompt and professional, this is only a suggestion.

The entire healthcare experience with Dr. Dam and her staff is excellent... friendly, competent, and actually interested in finding solutions to your problem. Actual healCARE. Rare and a great experience.

WALEED IBRAHIM, MD REVIEWS

My mom was hospitalized in an emergency situation and landed in the care of Dr. Ibrahim for her first procedure. This was a very scary and stressful time for all of us and he made my mom feel at ease and comfort the whole time during the procedure before and after he was amazing and my mom couldn’t stop talking about what a wonderful man he was and we were very pleased with the outcome and how smoothly the procedure went. He explained everything to her while I was not there & being that English is not her first language this was very helpful because she was able to explain the whole thing to me which only meant she understood exactly what he told her. He was very attentive and very Understanding. It was obvious he cared and he truly took care of my mom from start to finish. Thank you, Doctor Ibrahim! God bless you.

Dr. Ibrahim was AMAZING today. We had our first consult appointment with him. He was knowledgeable, thorough, and patient. He came well prepared as far as being familiar with our previous GI history. He showed empathy and took the time to answer all of our questions We would DEFINITELY recommend him to anyone needing help with GI issues.

I was treated very kind with everyone I dealt with! Everyone was cheerful and kind! Dr.Ibrahim is great I hope he will be my Dr. 2 years from now when I need my procedure done again.

GASPAR M. NAZARENO, MD REVIEWS

I cannot thank you enough for the absolute best medical care I have ever received in my 58 years of life. 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.

Best GI doc in town. Kind, compassionate and extremely knowledgeable. I've been his patient since he arrived. 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.

Over 10 years of care from Dr Gaspar Nazereno. Excellent care during my endoscopy, no pain at all after procedure every 3 years. Highly recommended.
