⭐ Patient Reviews

I had surgery with Dr. Mauricio and I'm doing very well, thank God! I would like to congratulate the receptionists who always attended to me with great attention and dedication: especially Erika, Damaris, and Jessica. I can only express my gratitude and give Kaiser Clinic a 10 out of 10.
In November 2025, I underwent appendicitis surgery with Dr. Juliano Joudatt. Since then, I have had regular follow-up appointments at the Kaiser clinic. I have no complaints about the care, professionalism, and compassionate treatment provided by the doctor, the secretaries, and all other professionals involved. I highly recommend him!
I loved the care I received from Dr. Fernanda. She is wonderful, very humane, and explains everything in detail! Before her, I saw four gastroenterologists, and none of them were able to treat me like she did, nor did they show any interest in helping me. I highly recommend Dr. Fernanda!
Excellent service, thank you! My surgery was scheduled for 8:00 AM, and by 8:30 AM I was already in the operating room going through surgical preparation, so everything was great and perfect 🙌🏽
Truly the best gastroenterology clinic in Rio Preto! Grateful to Dr. Kaiser, the best surgeon and a master of knowledge, he saved my life! Special thanks also to the receptionist Erika, for always providing us with personalized and caring service… thank you so much!
Dr. Juliano is an excellent professional and very humane! He helped me a lot in all stages of my Crohn's disease diagnosis, from surgeries to medication treatment. His entire team, including the secretaries, are super attentive! I am grateful to everyone!
I've been a patient of Dr. Kaiser since 2014. I had bariatric surgery and I'm being followed up by the team. I had argon laser treatment with Dr. Luis Gustavo and I recommend him. Everyone on the Kaiser team is attentive.
The Kaiser clinic's examination department operates with excellence in the quality of care, from Ana in scheduling, to the nurses, anesthesiologist, and Dr. Gustavo Quadros, who always perform the exams with great professionalism. A perfect 10 for this team! 👏🏻👏🏻👏🏻
I've been a patient of Dr. Kaiser for about 5 years, and the quality of care is excellent. What really sets him apart is the service. Secretary Aniele Monique is so cordial, polite, and kind. She handles all my questions and bureaucratic matters with great tact; that's true humanized treatment. Grateful to the entire team.
I am undergoing treatment at the clinic and would like to express my gratitude to Ms. Jessica, Ms. Damaris, and Ms. Erika for their excellent service and commitment.
Kaiser Clinic is a reference in the gastrointestinal system, colon proctology and other diverse specialties, not only in São José do Rio Preto - SP, but throughout Brazil (I am from the State of Mato Grosso) and they also serve many … More
