Dr Madriz was thoughtful and took plenty of time to educate me. He drew sketches, showed photos, and carefully explained things to me in a very helpful way. I did not feel rushed at all.
From the moment we arrived at the office, the receptionist treated us VERY kindly. As a new patient, she guided us through filling out the paperwork. We were very grateful. The doctor's assistant was very courteous. We felt her positive energy and kind treatment. Thank you. And finally, Dr. Madriz! WOW! He's one of the best doctors I've ever seen. VERY professional. He took the time to explain EVERYTHING in detail! He clearly demonstrated his GREAT knowledge and professional ethics. Thank you so much Dr. Madriz. Thank God for putting you in our paths!

Highly professional office, friendly staff. Dr. Madriz has treated me for 14 yrs with compassionate care. His medical assistant, Ms Hossen, provided quick answers to my post-visit questions. I felt both the doctor and his assistant were concerned for me as an older patient facing a painful office procedure and took extra steps to ensure my comfort.
Excellent care. The physician and everyone in the office just excellent. Highly recommend.
There was too much confusion on my insurance. Even when they were on my network.

Dr. Madriz is a great doctor, i.e. very knowledgeable, personable, and friendly.
The staff was professional and courteous. I was told to get there 30 minutes early and I was unable to. I got there right at appt time and had to finish paperwork, which took 30 minutes to be seen. Dr. Madriz gave me his undivided attention once in room with me.
Great doctor, He spent plenty of time with me and explained exactly what my issue was caused by and how to prevent it from happening again.
Glad I chose them again.
