William Utz
Patient
Just had my first visit with Dr. Koshiya at Dean Dental Studio. This was a consultation to get acquainted and see what work I might need to have done. Dr. K. was friendly and thorough. She gave me recommendations and options. She also found issues that my previous dentist had missed or ignored. So I plan to go back and have Dr. K. take care of everything.

Sheri T
Patient
I have been a patient of this practice for many years. Recently Dr. Arnold retired and I visited the office this morning. Ihadthe same fantastic hygienist and office staff. The new dentist was truly wonderful and she is in the process of helping me with some nagging dental issues. I trust her and am very impressed.
Bill J
Patient
Everything went very well and I had a cavity behind an old filling that was repaired immediately with very little discomfort. I quite liked my experience with this dentist and highly recommend her to anyone who needs a dentist that really cares about your teeth
Jerry P
Patient
Dr. Chaitali Koshiya did amazing work and I would recommend her and her office to all my family and friends. She was extremely thorough and explained everything very well! She was cautious and made sure I was not in any pain multiple times during my deep cleaning. 10/10 would recommend!
Tommy H
Patient
I was a patient of Dr. Arnold for many years and was genuinely sad to see him leave. That said, after meeting Dr. Koshiya, I felt completely at ease. She is approachable and clearly very knowledgeable. I’m confident in her care and will absolutely continue coming to this dental office.
Angelo R
Patient
Dr. Koshiya is a very competent and thorough dentist. My wife and I were her patients back when she practiced in Crystal Lake. Needless to say we are glad to have followed her to Dean Dental Studio. The staff there is very competent and caring. I would recommend Dean Dental Studio without any reservation.
Joan L
Patient
Dr. Koshiya was able to see me the same day when I called about an issue I was having. She took the time to clearly explain and to show me what was happening, and she reviewed what my options are going forward. She also contacted my insurance company for pre-authorization so I will know what is covered. I feel very comfortable with Dr. Koshiya.
