Who is Alexander Villareal? Was that the intern in on the video appointment? The doctor was a great guy - the intern sat there like a disinterested statue - added nothing. Said nothing. looked judgy. Clearly not interested in the field.
- 1 out of 5 starsReviewed on 6/6/2026
The employees are great, 10/10 experience from them! I would get the help they recommended but the cost is way too much and I would rather die than be in massive debt to you. Healthcare should be free.

Not a fan of my chart.

This experience was good, but when my cardiologist wanted me to have a take home sleep test the same day because I was experiencing severe heart failure, I had to wait for an appointment and then was scheduled six months out for a sleep study. I needed to go outside of La Crosse to have my sleep study. Is this treatment of patients consistent with your commercial that a little empathy goes a long way. I don't think so.

Choppy. I was unsure of the outcome until I heard from me provider.

Wish they had me sign forms while I was in the office. I can't do internet stuff without asking someone to do it for me.

Do not like the phone visit probably will not do that again. I needed to have him book my tube mask. Store will continue seeing him next time.

Saying my appointment was at 1:00 and then having to wait until 1:30 to speak with the provider because that is when it was scheduled was very frustrating. If using online please make the time frame more realistic.

I haven't heard anything after the sleep study
- 5 out of 5 starsReviewed on 1/27/2026
I am not a high tech person. Able to follow the directions concerning questions before video time until closer to ending. Called and the staff person that helped us maneuver through this and then waited extra minutes to guide us through to live video was so patient and kind we cannot thank her enough! Video with doctor went good. My wife and I agree that in person is what we would prefer. We got flustered with trying to operate our phone and respond when needed. We think more clearly when 1on 1 in person because we would not focus on what we should do next. The staff and the doctor were all very exceptional but we are the ones that are not techy.

Dr. V took time to explain alternative face masks even though this might have been referred to the medical supply business. I feel I can go into that situation confident in what I'm looking for to improve the usage of my CPAP. Warm, friendly, caring. Great experience.

The gentleman doing my sleep study was amazing as this was my 3rd sleep study and he is the first one to explain things so I understood exactly what was going on.

Very satisfied today with both appointments I was involved with today. My brother neurology, and myself with the sleep study. Both appointments provided the information I/we were seeking, knowledge I didn't know and a plan forward in addressing the issues that are presenting a problem with moving forward with our needs. Told my brother on the way home that I felt we accomplished so much today, checked off many boxes of needs.

This was my initial visit with Dr. Villareal, and I was originally scheduled with another provider who was ill on the day of the appointment.

Very detailed, listened to my feedback, and did a nice job of educating me.
