I recently visited Marsh Creek Dental to have my fillings done. I found Dr Kumar to be friendly, personable and highly professional. He was very patient, informative and answered all my questions. The entire team at Marsh Creek Dental are very eager to help and provide a great service. I highly recommend a visit for your dental needs.

Very kind dentist/hygienist. Showed me my cavities in pictures from some device. Then cleaned my teeth and did my fillings in a very timely efficient manner while still being aware of any distress I might feel. Good people all around.

Years ago I was involved in a very bad car accident that necessitated major dental work, both in office and under surgery. Needless to say I’ve seen my fair share of dentists. By far Dr. Kumar has been the best I’ve ever seen. Also, his staff is top notch! I highly recommended Marsh Creek Dental!!
