I thought that Dr. Marler and the staff in the offices have done an outstanding job as I'm a new patient. Also, I made a boo-boo and I pressed the wrong button on number one. It should have been four. Thank the office for their courtesy and they got me in so fast. It was astounding. Thank you so much for all of your kindness. I appreciate it. Bye.

I waited almost a full year for my first appointment with doctor Marler. We relocated in march of 2025 so it would have been great if I could have gotten an appointment with Dr Marler sooner but as it turns out, I am very happy with the visit and think Dr Marler is an exceptional Dr. I am pleased with his performance and would recommend him to anyone. The check in was great and the nurse care was top notch.

Able to see my doctor, PA or NP in a timely manner. I had to go to an urgent care center the first time to be treated for my respiratory condition. I have asthma and not getting a respiratory infection dealt with quickly is a real problem for me. Very disappointed that wasn't made to happen.

I would suggest that every time I use a Prisma doctor or facility, you don't survey me afterwards. I've seen quite a few doctors and facilities and it's rather stressful, but I'm very happy with all my Prisma doctors.
