Dr. Theunissen is always very nice during the visit. She makes me very comfortable while examining me. She is very clear on what she finds during the exam. I would give her a ranking of 10 out of 10 and highly recommend her to everyone

Spent no time discussing different care plans, barely looked at my skin, did not ask for a history. Interrupted me, dismissed my concerns. I was extremely frustrated that I waited for this appointment for over a month and it was finished in under ten minutes with me having little to no understanding of the medicines I was prescribed.
- 5 out of 5 starsReviewed on 6/24/2025
Dr Theunissen has always been kind and helpful! I've have been recommending her to family and friends.
