approach in pursuing his career in the building industry. Focusing on one trade, Keith saw a demand for hardwood flooring installation and refinishing. He then formed the company Seirra Hardwood Floors at age 20 and the majority of his revenue was generated being subcontracted by other flooring companies. Knowing that this was not the career of choice, after 2 years of successful service he dissolved the company and chose a new path as a framing subcontractor by forming North Jersey Framing Co. The new company grew as he framed houses all over northern New Jersey with his crews and developed a good reputation as an expert home builder. He established a wide range of relationships with builders, commercial property owners, home owners and suppliers in 4 counties.  After many requests to run job sites, Keith used his crews to complete full additions and homes swiftly and efficiently for many clients. Caught between two career paths Keith formed a secondary name, Mainstreet Renovations, and developed a loyal following for both his framing services and home remodeling services. He recently combined these two services to one name, North Jersey Pro Builders. 

Keith Mellen has been an established home builder and renovator since 1998 and plans to continue to maintain his hard earned reputation for many years to come.
