About Us Trevdan Building Supply’s first day of business was May 17, 1982. The name Trevdan is derived from the combination of Larry and Valerie Kanavy’s first two children’s names – Trevon and Danielle, neither of whom are associated with the business. Tim, Trevon and Danielle’s younger brother, works side by side with his father in the family business. Larry Kanavy – Founder, President, and Treasurer of Trevdan – has been in the building supply business for 53 years and believes the key to the company’s success can be traced to its employees. “I have the finest employees and the best customers in the business,” Larry says. “Customer service is our #1 priority. Ask us a question and we’ll answer it. Come to us with a problem and we’ll do our best to solve it. At the end of each business day, you will be better off having dealt with Trevdan and we take great pride in that.” If you are doing business with us now, thank you. If you aren’t, please give us the opportunity to provide you with excellent service and fair prices. Together we will build a better world.
