Bart grew up in Palm Harbor, FL with a family that had a passion for dentistry. His father, Dan Knellinger DDS, has a practice and has been a pillar of the community for over 30 years. His mother, Jennifer Knellinger, has worked by Dr. Knellinger’s side in the office every year since they began seeing patients and is the catalyst behind the growth of the practice. Bart has three sisters, Stacey Verkler, Carol Bou-Sliman, and Jill Schmidt. Stacey is also a dentist and is in practice with Dr. Knellinger. Carol is a new graduate from the University of Louisville School of Dentistry and is in practice with Drs. Knellinger and Verkler. Jill is an accomplished attorney in the Tampa Bay Metro area.
When Bart graduated high school he did not take the same path as his family. His dream was to be an entrepreneur and he believed the most important skills he needed to hone were creative thinking, communication, and determination. There is no better way to manifest all of those aptitudes than to put yourself in a situation in which you have no choice but to succeed.
