Personal Note From Dr. Hove
To My Wonderful Patients,
It is with mixed emotions that I am writing to let you know I have made the difficult decision to leave clinical dentistry, which will be effective July 15, 2026. Due to some issues with my wrists and hands, I am no longer able to continue providing the dental care you deserve.
Serving you and your family for the past 20 years has been one of the greatest privileges of my life. I have had the pleasure to see and treat many of you for years, and you have become like friends. I have deeply valued the relationships and trust you have placed in me and I will miss you greatly.
Thank you again for the wonderful memories and the opportunity to be your dentist. I wish you and your family a lifetime of health and happiness.
Sincerely,
Lindsay Hove Grethen, D.D.S.
