Dr. Barrett Straub

Barrett Straub is the CEO of Smile Source, a community of independent dentists working together to protect and grow private practice dentistry. A dentist by training and an advocate for dentists at heart, Barrett brings a deep respect for the profession and a personal understanding of the challenges that come with running a private practice.

For almost 20 years, Barrett owed a fee-for-service general and sedation practice in Port Washington, Wisconsin. Like many of his peers, he worked hard to build a practice that reflected his values and served his community well. Along the way, he developed a passion for leadership, team development, and the kind of business strategies that help great dentists succeed on their own terms.

In 2017, Barrett joined ACT Dental, where he helped guide the company's coaching and education efforts. After selling his own practice, he became ACT Dental's CEO in 2023. In 2025, Barrett led the acquisition between ACT Dental as it merged with Smile Source, and today Barrett leads the combined organization as CEO with a focus on helping dentists stay independent, grow stronger together, and build careers they're proud of.

He's a graduate of Marquette University School of Dentistry and has trained with institutions like the Spear Institute, LVI, DOCS, and the Seattle Study Club. In 2017, Marquette honored him as their Young Alumnus of the Year. He has served in organized dentistry within the Wisconsin Dental Association as a Board of Trustees member and at the ADA level as a House Delegate and a member of the Council on Governmental Affairs. 

Outside of work, Barrett lives in Wisconsin with his wife, Katie, and their two daughters, Abby and Elizabeth. He's a big fan of the outdoors, loves to be in a tree stand deer hunting, a decent golfer on good days, and a curler during the long Midwest winters.
