Dr. Sherri Poettker, DMD

I consider myself extremely lucky to practice dentistry! There are so many aspects of my dental career that make it wonderful including making a positive impact on my patient’s lives. I love being able to create the perfect smile that someone has always dreamed of and seeing what a difference a bright smile can make in my patients lives. I also look forward to meeting new people and having them become a part of my extended family at Lakeside Dental. We have a wonderful team at Lakeside Dental that is truly compassionate and strives for excellence at every opportunity. It's a joy to work along side of each and every team member. 

 Sherry Poettker, DMD is a Family Dentist in O'Fallon,MO

Backgrounds & Interests:

            I am a native of Carlyle, Illinois.  Growing up in a small town enabled me to learn about hospitality and how I want to 

treat people .  I was raised in a large family, and enjoy spending free time with family members.  I enjoy outdoor activities including camping and boating.  During the summer months, I spend most of my free time skiing and wakeboarding on the local Missouri waterways.

            My husband and I are excited about living in this growing area.  The kind residents that we have met over the past couple of years have helped us fall in love with this community.  I hope that you will become part of our extended family at Lakeside Dental.
