Team of Experts


James Renehan / President & CEO
Ever since childhood, company President & CEO Jim Renehan has had a dream of being a home builder and has had a passion for building homes. To Jim, building homes is not a job; it is a lifelong passion. With an entrepreneurial spirit instilled by his father, he began with small projects, which led to more notable ones, with each venture getting more complex. Today, Renehan Building Group has developed a reputation of unparalleled customer service, quality and integrity, by building homes of distinction throughout Chester, Montgomery and Delaware Counties.
Jim, along with his design team, will personally design your home to fit your lifestyle. Jim will review all details with you often throughout the project to keep you informed and everyone on the same page. RBG’s mission is to be the best builder in the area, not necessarily the biggest. Jim hand picks the best team in order to build projects that speak for themselves.
Jim previously worked for a small, family-owned corporate paint company for 15 years that prepared him for the business side of the construction industry, which made his entry into home building a success.
