Brendan Duffey

Sales Associate


Brendan Duffey has spent his entire career in the real-estate industry as both a licensed realtor and a Certified Residential Appraiser. With more than 24 years of real-estate experience, he brings a wealth of personal and professional knowledge to his clients. He likes to take the seemingly complicated process of buying or selling real estate and make it not only understandable but profitable. Brendan is passionate about real estate — and knows its importance as a generational wealth asset.

In 2005, Brendan created his own company, Excel Appraisal Group, and later became a licensed real-estate agent. Although he now helps clients find or sell their homes, he still enjoys helping agents and lenders with appraisals. Brendan holds the esteemed Accredited Luxury Home Specialist designation and has served his community in Celina, Texas, as an appointee to the city’s Building & Standards Commission, where he helped homeowners bring their properties up to city standards. Brendan is a graduate of the Collin County Law Enforcement Academy and was a licensed peace officer before joining the real-estate industry.

Brendan has called North Texas home for 40 years. He lives in Celina with his wife, Cheryl. They have two grown children, Whitney and Brendan Paul. In his free time, Brendan enjoys paddleboarding and basketball — and hiding golf balls on the golf course for other golfers to find.
