David Kowalski

David Kowalski


David Kowalski wants to live in a world filled with innovative and enthusiastic real estate agents, where emails are short, transactions close early and clients love their UBG agent. As CEO, he helps real estate agents grow their business into rewarding careers through collaboration, education, and determination.

David pulls from 25 years of technology and financial experience interfacing with sales and marketing teams to help agents incorporate technology and sales systems into their business. Although he thinks software is usually the answer (and codes for fun), he can’t help but admire the smile real estate agents can bring to faces of their clients when they find the perfect home. When he’s not helping agents use technology, you can find him re-watching any season of Shark Tank, testing Amazon’s same-day delivery promise or walking way too far in the desert heat to find his car ( that is almost an obsession). David grew up in Toronto and has called Gilbert, AZ home for the past 12 years.

Cathy Swann

Cathy Swann

Designated Broker

Cathy’s real estate success stems from her belief that the business is about people, not transactions. (A sense of humor also helps.) She carries this same philosophy into the role of Designated Broker, where she knows that UBG’s success depends largely on the relationships our agents build with their clients.

Growing up in Tempe, graduating from ASU, and raising her family here have given Cathy unique insight into the benefits of East Valley living. It’s also given her a healthy appreciation for spending summer weekends in Flagstaff whenever possible. Cathy enjoys coaching first-time marathoner runners and just hanging out with her husband and 4 children.
