Kristin Guenther, DDS

It is with sadness and excitement that I am announcing my retirement from practicing dentistry. I will deeply miss seeing all of you and catching up on what is going on in your lives. Many of our connections go back more than 40 years! I always felt priviledged to work with and be trusted by such a talented and interesting group of people. It was a great career filled with great people like you and our team, a team my husband and I developed over 25 years as D&G. Our greatest joy has been to bring others to a better place in their lives. Health, confidence, beauty and overcoming life’s hurdles were our mission. Thank you with all my heart!

You are in good hands with the team at DGY! As a means of ensuring continuity of care, I will keep sharing my knowledge with the practice as questions arise concerning my patients and areas of expertise.

With sincere appreciation again, I send you a virtual hug.

Kristin Guenther, DDS
