Grandville Pediatric Dentistry
Your Child’s Dental Journey Starts Here
Welcome to Grandville Pediatric Dentistry! Drs. Michael Demeter, Sally Kotani, and Agata Lefere strive to make your child’s dental health journey a positive one. We’re here to help every step of the way.
Dear Patients, Colleagues, and Friends
It is with both gratitude and excitement that we share some important news about Grandville Pediatric Dentistry.
More than 20 years ago, Dr. Michael Demeter purchased this practice from Dr. Wayne Pierce and began a journey that has shaped Grandville Pediatric Dentistry into the caring, family-centered practice it is today. Throughout his career, Dr. Mike has had the privilege of caring for generations of children and building lasting relationships with families, colleagues, and friends in our community.
After much thought and reflection, Dr. Mike has decided to retire from dentistry at the end of July 2026. While it is never easy to say goodbye to a profession he has loved so dearly, he is looking forward to spending more time with his family and friends and embracing new adventures and hobbies.
Although we will miss Dr. Mike’s contagious energy, laughter, and unforgettable sense of humor, we are incredibly grateful for the compassion, dedication, and joy he has brought to our practice and the countless young lives he has touched over the years.
As we begin this new chapter, we want to reassure our patients and families that the heart of our practice remains unchanged. Dr. Sally Kotani and Dr. Agata Lefere have proudly served alongside Dr. Mike and will continue their commitment to providing the gentle, safe, and exceptional care you have come to know and trust.
We are also excited to share that Grandville Pediatric Dentistry is entering a new chapter of ownership, with Dr. Agata Lefere leading the practice into the future. We are confident this transition will be seamless and that our team will continue to serve the children, families of Grandville and the surrounding communities with the same warmth and dedication that have always defined our practice.
From the bottom of our hearts, thank you for trusting Grandville Pediatric Dentistry with your children’s smiles throughout the years. It has been our honor and privilege to be part of your families’ lives. Please join us in celebrating Dr. Mike and wishing him a happy, healthy, and well-deserved retirement.
With gratitude, The Grandville Pediatric Dentistry Team
