Dr Álvarez is very thorough in his evaluations and makes certain to personally follow up particularly after procedures. I have had a few procedures done with the Group and Dr Alvarez and I'm so pleased with his level of care.
Good caretakers and they open my eyes to take care of my body more...
Scheduled for procedure at 11am but didn't happen until 125pm. Other than delay dr. Alvarez and all the nurses and staff were great and made me very comfortable
Very satisfy with service and care for my medical condition. Very patience
SAGA has been my choice for many years. Ms Becker has been an asset to the practice. A great place to be when you need care.
My PA Venessa was very helpful and very professional. Dr Otero and his staff have my utmost confidence. Thank you! .
Dr. Hernandez was excellent. She spent time listening, was very thorough and knowledgeable, took as much time as I needed to answer all questions, ordered tests to get at the problem and had good follow up. All the staff were kind, helpful and efficient as well! Thank you!
My recent visit on 2/23 was awesome. Love Dr John Jacob Alvarez and coordinator Eddy. They’re like friends or family. Always very concerned with my medical conditions. If it wasn’t for them and Eddie’s constant persistence,I wouldn’t be receiving my biologic meds with a subsidize program at no co-pay cost. I look forward to my quarterly visits.
My experience with this office has been great for the past 6 months. Everyone is kind and always professional. From the front desk to the nurses and doctors I thank you for taking care of me.
The entire process from scheduling the colonoscopy, all the way up to learning the results of same, was smoothly handled. Even the preparation process! 🥴
But the peace of mind that comes from hearing that no polyps were found makes the entire process worthwhile. In addition, hearing Dr Otero say that my next exam will be in FIVE YEARS made me feel even better!
