Michael J. Rabena, Sr.


Michael J. Rabena, Sr. has been in the construction field for much of his life.  His family has been builders and general contractors for almost forty years.  In his teen years he worked after school and weekends and developed a love for the industry.  Michael graduated from Saint Joseph’s University where he earned a Bachelor of Science degree in Chemistry and a Master of Science degree in Analytical & Physical Chemistry.  After graduate school he worked for E.I. DuPont as a research chemist. After four years Michael decided that his love for construction was still there.  He left DuPont and joined his family’s general contracting business. They started a construction management company and development group that Michael spearheaded.  The company performed larger scale projects such as building schools, office buildings, and large custom homes. He was involved with the family business as a partner for eleven years.  In 2011, he decided to venture out on his own and formed Terra Firma Builders, LLC.  Over time Michael realized that there was a client need for property management.  In August of 2013, TFB Property Management, LLC was formed.  This division focuses on complete residential and commercial property management.  Michael is involved with every project Terra Firma Builders, LLC and TFB Property Management, LLC  are working on at any given time.
