Everything was good, but I wish it were closer to Richland Center. Would like to see our office here reopened; there are plenty of people here who would appreciate itl

Eventing was great except when i left i could still smell perfume/ fragrance on my face from the device, i assume from the cleaner though it smelled more like cologne. I had to go home and immediately wash my face to stop my reaction

Great staff at Hillsboro Eye. Just a gentle reminder that sometimes we need to talk slower, louder, and with fewer words for older people to understand and process.

All staff very personable & friendly. Very good explanation of status of my eye exam. Non-pushy about need for new glasses at this time, yet clear answer about some changes that could warrant new prescription.

2nd year receiving eye care @ Hillsboro. 5 different care givers assisted me yesterday. Without exception, each are to be commended for the services they provided. They work as a team. Look forward to my follow-up visit in the fall.

very clean

Dr Thom had a very upbeat demeanor and made you feel comfortable from the minute he walked in the door. He explained diagnoses and also took the time to show me pics online to help me better understand what was going on. His staff were equally friendly and welcoming! Would definitely recommend them to friends and family!

I appreciate the care I receive at the clinic. I'm sorry they left Richland Center but am glad Hillsboro is close.
- 5 out of 5 starsReviewed on 3/12/2026
I am not familiar with using Emplify's MyChart. I think there should be more complete instructions on how to use it rather than an assumption that you already use it. This in way reflects on the Hillsboro staff.

I have trust in the doctor that examined me and trust in his assistant. I feel I had a thorough exam from both individuals. Also good assistance from the entire office staff.

I was able to get an appointment same day due to a cancelation, which I very much appreciate. Check in was hectic as the receptionist was juggling 3 of us with different needs at the same time. She was polite and professional while under pressure.

The eye clinic is awesome! Welcoming from walk in to walk out!! Only wish Anthem would let us use the in house eye glasses store. As it stands I have to go out of town to fill my prescription.

the pre check in was way to long and repeated questions. would rather do it in the office instead of on line, confusing for older adults that don;t use cell phones that much.

It was a very good experience. The girl that did my eye report was very good. Last year, that girl was terrible. So I'm so glad they had a new girl with my eye charts. And the doctor was very good. Thank you. Bye now.
