Life & Hobbies

“I have an amazing husband and two adorable dogs. My husband and I are originally from Northwest Arkansas and recently moved to Lee’s Summit. We absolutely love it here! I enjoy painting, sculpting, and crafting when I’m not outside working on my garden or playing with my dogs. Traveling the world is also something I’m passionate about. But my true passion is dentistry and making people feel confident and joyful in their healthy smiles.”
