Everything was great!
- 4 out of 5 starsReviewed on 3/5/2026
The nurse who attended to me took my BP manually after using machine. The machines you have in all Prisma facilities are always high and inaccurate.
- 5 out of 5 starsReviewed on 3/4/2026
Everything was fine and they don't have to change anything from what I can see

Nothing. Dr Marler & his nurse are awesome. They answered my questions throughly.
- 4 out of 5 starsReviewed on 2/8/2026
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.
- 5 out of 5 starsReviewed on 2/7/2026
Keep up the good work
- 5 out of 5 starsReviewed on 2/11/2026
The staff is welcoming, caring, and helpful. Dr. Eric listens to your questions and is very thorough.
- 4 out of 5 starsReviewed on 2/6/2026
Asked me if I had questions or concerns, rather than me bringing my issues up.
- 5 out of 5 starsReviewed on 2/4/2026
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.
- 5 out of 5 starsReviewed on 2/1/2026
Dr Marler took proactive action by ordering additional tests to ensure my future health.

Everyone from the veinapuncture tech to Dr. Marler was courteous and engaging. I am hard pressed to think of a way that this routine visit could have been improved!

Appreciate Dr. Marler
- 5 out of 5 starsReviewed on 1/20/2026
Nothing comes to mind. Dr Marler is an excellent doctor and one that cares deeply for his patients. Always researches all Prisma tests / other doctors input and is on top of my care.
- 5 out of 5 starsReviewed on 1/18/2026
All was great.
- 5 out of 5 starsReviewed on 1/18/2026
Let the doctors relax and spend a little more time with each patient because I always remember something I wanted to ask as soon as I leave!
- 5 out of 5 starsReviewed on 1/18/2026
This appointment was completely satisfactory and full of valuable information for my continued recovery.
- 5 out of 5 starsReviewed on 1/18/2026

Don't change anything.
- 5 out of 5 starsReviewed on 1/18/2026
The visit was fine. Just a yearly checkup. Everything went well. Found out Dr. Marler is a doctor to a group of aging bass fishermen. That's a big plus with me!!!!!!
- 5 out of 5 starsReviewed on 1/17/2026
I can not think of anything.. it was a great experience!

Excellent experience - complete confidence!

I can not think of anything! It was a pleasure being treated there!!
- 5 out of 5 starsReviewed on 12/16/2025
The staff is great but Prisma has the doctors so tightly scheduled that it interferes with the opportunity for patients to bring up new concerns. The doctors don't have time to ask "what else is on your mind or concerning you about your health" because Prisma has them on a schedule that rushes them off to the next appointment. As a patient I need to be bold and strong enough to bring up a new concern on my own if I find the doctor is ready to wrap up and move on when I still have something on my mind.
- 5 out of 5 starsReviewed on 12/15/2025
Exceptional care
- 3 out of 5 starsReviewed on 12/14/2025
Not sure if 15 minutes, is adequate time for a yearly visit, or just time allocated for Medicare patients?
- 5 out of 5 starsReviewed on 12/12/2025
Dr. Marler and his staff were amazing, caring, and knowledgeable! They listened and provided excellent care!

Nothing more needed. Dr. Marler is 1 in a million. He is absolutely the best of the best!
- 5 out of 5 starsReviewed on 11/23/2025
I would like to be able to see Dr Marler when I am sick instead of having to see NP. I am aware he stays booked, but he is my physician and the Best!
- 5 out of 5 starsReviewed on 11/22/2025
No changes needed. I appreciate the quick response for an appointment as this was a follow-up from the hospital. I am always treated well at this office.
- 5 out of 5 starsReviewed on 11/22/2025

Im satisfied with the Dr visit.
- 5 out of 5 starsReviewed on 10/26/2025
None necessary
- 4 out of 5 starsReviewed on 10/27/2025
More knowledge of my medical history.
- 5 out of 5 starsReviewed on 10/26/2025
I believe that when you're there for your annual visit or yearly visit, there should be more time allotted. I feel bad actually for the doctor because I know usually you have a lot more questions and I feel like the time frame was not really allocated properly between patients. That's just basically how I felt. However, Dr. Marler was awesome and answered all the questions I needed answered and I know I can always reach out to him through the portal. Thank you so much.
- 5 out of 5 starsReviewed on 10/25/2025
The computer system seems to mix up my prescriptions. No fault of the staff.
- 5 out of 5 starsReviewed on 10/24/2025
Care was excellent!
- 5 out of 5 starsReviewed on 10/24/2025
I was taken on time but waited more than & half & hour to see the Dr. Then it felt like he was rushing to get to the next person. I left they're not knowing why I was experiencing feeling off balance. This is not like him.
- 4 out of 5 starsReviewed on 10/24/2025
Everyone did what they needed to and were very nice!
- 5 out of 5 starsReviewed on 10/24/2025
Dr Marler is hands-down one of the best doctors I have dealt with in the Prisma network. Took the time to review my medical history prior to the visit, listens and genuinely ask questions to get to know you.
- 5 out of 5 starsReviewed on 10/23/2025
I was again thoroughly impressed with Dr. Eric Marler's medical knowledge and professionalism. The nurse was also very professional. Keep up the good work!
- 5 out of 5 starsReviewed on 10/18/2025
I don't know of anything that could have been done differently. Everything was handled flawlessly.
- 5 out of 5 starsReviewed on 10/14/2025
I really can't think of anything. Dr. Marler is always the best taking the time to explain and go over everything and listen to any concerns I might have.
- 5 out of 5 starsReviewed on 10/12/2025
There is always room for improvement but at this time I think Dr. Marler and his team do an great job

All aspects of my appointment were fulfilled.
- 5 out of 5 starsReviewed on 10/5/2025
Hire more Dr.'s. They seem very short handed
- 5 out of 5 starsReviewed on 10/4/2025
Keep up the good work ?
- 5 out of 5 starsReviewed on 10/3/2025
Every one & everything is just right at Prisma

- 5 out of 5 starsReviewed on 9/20/2025
This team is just right for me and my wife

No changes required
- 5 out of 5 starsReviewed on 9/19/2025
No. Dr. Marler and the staff here are wonderful and efficient. I was seen on time. Dr. Marler knew all my history I had sent him since last visit. He listens, is knowledgable, compassionate and kind. I very much appreciate having him as a provider in an area that is really lacking in the standard primary care. I feel well taken care of and he will do everything to help me even between visits, he is always responsive. He wants to help.
- 5 out of 5 starsReviewed on 9/20/2025
I do not have any recommendations because I always receive exceptional service while I'm there.
- 5 out of 5 starsReviewed on 9/19/2025

I think you are doing the best you can.
- 5 out of 5 starsReviewed on 9/15/2025
Drastically need to update patient bathroom in the lab. The flooring appears dirty because of staining. There is no sink. It looks like something that should be in a bus station not a healthcare facility.
- 5 out of 5 starsReviewed on 9/14/2025
All was good
- 5 out of 5 starsReviewed on 9/14/2025
Give the doctors more time per patient it is offensive the length of time it takes for the doc to come into the room. An hour wait is ridiculous .
- 5 out of 5 starsReviewed on 9/12/2025
Everything met my expectations. Thank you.
- 4 out of 5 starsReviewed on 9/9/2025
My visit was somewhat rushed because I needed to get to the lab before the staff left for the day.
- 5 out of 5 starsReviewed on 9/7/2025
Everything was perfect!
- 5 out of 5 starsReviewed on 9/7/2025
My chart needs help.
- 4 out of 5 starsReviewed on 9/7/2025
The provider was pressed for time to keep within our 10 min limit. We did not have time for me to address some of my issues
- 5 out of 5 starsReviewed on 9/1/2025
I appreciated that I was offered the alternative blood pressure check. The BP devices throughout Prisma always give ridiculous high readings. That's been my experience.
- 5 out of 5 starsReviewed on 9/1/2025
This is a wonderful provider and his staff is excellent.
- 2 out of 5 starsReviewed on 8/31/2025
Would have thought someone there could helped more and we would have had a need met that without without having to schedule 5 days later. Felt like it was another way it can be all about money.
- 5 out of 5 starsReviewed on 8/26/2025
I was treated with respect and I trust those who cared for me.
- 5 out of 5 starsReviewed on 8/25/2025

- 5 out of 5 starsReviewed on 8/22/2025
I was really impressed with my new doctor . He looked up my records back to when I had my heart attack. And he took his time with me and asked if I had any questions and I didn't but he said if I thought of some questions I could get on my chart and ask him. Very impressed with dr. Marler
- 5 out of 5 starsReviewed on 8/22/2025
Excellent interaction and services.

Everything is great.
- 1 out of 5 starsReviewed on 7/21/2025
I did not feel like the doctor genuinely cared about me as a person. The visit was very rushed, and I do not feel like he was listening. I did not even have an opportunity to discuss other issues that I was concerned about regarding my Libre. I could tell that he was ready to get out of the office and onto the next person.
- 5 out of 5 starsReviewed on 7/20/2025
Everything is very professional!
- 5 out of 5 starsReviewed on 7/18/2025

The lab closed just as I was ready to get my blood drawn. I had to go back the next day. This was very inconvenient
