Origins

​

As a teenager, Frank Reis started doing odd jobs around his family home. Eventually this lead to him upcycling discarded antiques he would find, refurbishing them, and giving them as gifts to friends and family. A few years down the road, during the Carter administration, generous grants were provided to businesses and homeowners to aid in solar panel installations. ​Frank spent many years doing solar auditing and installing solar hot water batch collectors during that time, which is where his interest in sustainability and green building practices really took off. Those years of experience lit the spark for what eventually became Walnut Tree Construction. Some years later his son, Joe Reis, joined the team and today
Walnut Tree Construction is a thriving family business with a close knit team of contractors and support staff.
