I've been seeing Dr. Bentkowski since 2015 and he is great.  He cares about his patients and listens to their concerns.  He doesn't rush to get you out of the office, and has some good jokes now and again to lighten the mood.  I have recommended him so many times, and nobody has said anything bad about him ever.

Overall Rating: 5.0 2022-12-27

He takes the time to listen and he evaluates all possible issues.
