Care Philosophy
My goal is to build lasting relationships with my patients by taking time to listen, explain and empower them to understand their eye health. I strive to make each visit comfortable, collaborative and centered on each patient's unique needs.
Personal Statement
My wife and I enjoy living in Prairie du Chien and try to visit as many different Wisconsin Supper Clubs as we can. I enjoy all the outdoor activities, including hiking, fishing and hunting with my dog Frankie. When I'm not outside, I like to spend time woodworking, completing home improvement projects and tinkering in the garage.

Dr. Flunker is the best. I would very much trust him with my care and recommend him to everyone.

It would be easier for me if all the visits I have at Prairie du Chien, Healthy Hearts would not be included on my appointments page. They fill it up and I have to search through all of them to find my medical appointments.

Dr. Luke Flunker is Absolutely AMAZING ! Actually, the best optometrist I've ever been to. Explained everything to my understanding. Clean facility. Friendly staff. Wonderful. Thank you !
- 5 out of 5 starsReviewed on 8/23/2026
I'm a new patient and everyone was very nice and helpful. The lady that checked me in even walked me to the waiting room since I was new and showed me how to follow the foot prints on the floor. Luke was very good and explained every question I had to me. I had to pick out glasses and the gal that helped me listened to what I was looking for and helped me pick the perfect pair. It was a very good experience!

Everyone was very nice. My appointment was at 1:15 I got in for my appointment at 1:30. Everything went very smoothly.

I arrived early for my 7:30 appointment and didn't realize I was the first patient of the day. While I was standing outside, I received a prompt to complete online registration, but the system kept giving me an error message, so I stopped trying. When the front desk staff member unlocked the doors, there was no greeting or acknowledgment. I followed her to the desk and the first thing she said to me was that I needed to sign a form. A friendly greeting goes a long way, especially first thing in the morning. Even a simple "Good morning" would make the check-in experience feel more welcoming. Everyone else I interacted with was wonderful.

I always feel so welcome when I come. Everyone always makes me feel like they genuinely care all the way from sign in to ordering glasses. I especially appreciate the help with the glass frame selection. Also just love Dr Flunker and how personal and helpful he is. He is fun but professional at the same time. I really appreciate the care I receive.. Thank you

I did not know that my eyes would be dilated at this appointment. I was asked to pay after the appointment and I was unable to read any paperwork or fill out my check. if the clinic knows the patient will have their eyes dilated paperwork should be done in advance.

The only issue i had was when I was trying to check in and started talking to the lady helping me, the other lady to her left (when facing the desk) talked so loudly that I couldnt hear the person I was talking to. I could hear all of the other patient's conversation simply because the receptionist spoke so loud. I tried dtonday something but no one could hear me. I would recommend a divider desk like they have in Lacrosse at the clinics so they HIPPA isn't being violated along with it interfering with others trying to check in/out.

The multiple reminders and other requests a week prior to the appt for the check in process is excessive. I did all do the requests ahead of time and when I arrived I had to wait in line for over 12 minutes to do the check in anyway. Multiple patients checking in at the same time created a bottle neck at the same time during check in. The appt was great but the check in process was not favorable at all.

I had a poor experience with Trudy who had checked me in. I had gotten mine and my son's appointment times wrong and she made me feel belittled and unheard and talk to as if I was a child. She wasn't even the one who was checking me in. I was being checked in by another gal, and she started talking over the other gal to me. I had to tell her I didn't want to talk about it anymore and I just wanted to finish being checked in, in order to get to my appointment. Also, by the way I had checked in online due to previous poor service. I am extremely unsatisfied with her service and this isn't my first time experiencing poor service with the Gundersen eye clinic front desk service. I would like to make it clear that Dr. Flunker and the gal who conducted the eye check were great.
