John Wilder Quillen, Jr., P.E., MBA, Founder at Marque Engineering, has been recognized by Marquis Who’s Who Top Engineers for dedication, achievements, and leadership in commercial engineering.

After obtaining an Associate of Science in engineering technology from Edison State Community College in Piqua, Ohio in 1999, Mr. Quillen followed with a Bachelor of Science in electrical engineering from Wright State University in Dayton in 2003. He later continued his education with a Master of Business Administration in management, organizational structure, strategy, business analytics from Northern Kentucky University in Highland Heights in 2016.

From 2003 to 2014, Mr. Quillen excelled as a director in charge of retail, commercial, grocery and civic markets with KLH Engineers in Fort Thomas, Kentucky, a nationally-ranked firm providing award-winning mechanical, electrical and plumbing engineering services. He then served as a senior electrical engineer with ProLink Staffing in Cincinnati, where he performed professional engineering consultant services for three new Department of Transportation County Maintenance facility campuses.

In 2015, Mr. Quillen founded Marque Engineering in Cincinnati, which provides a full range of professional engineering services, including mechanical, electrical and plumbing, to a diverse range of clientele across market sectors. The firm was recognized as a 2020 Fast 55 Company by the Cincinnati Business Courier and as a 2020 and 2019 Top Engineering firm by Building Design+Construction Magazine’s annual Giants publication.

According to Mr. Quillen, he became involved in engineering because while he was growing up, his father was really interested in science fiction, and the two of them would watch the “Star Wars” films together. Even when younger, he was a thinker and remembers being fascinated by the characters and how the doors on the ships opened and closed. Math and science have always been easy for him. Mr. Quillen maintains that the attributes that have played a role in his success are the ability to communicate effectively and make a fast and wise decision to move things forward. Likewise, he has had great attention to detail and organization. In the coming years, Mr. Quillen intends for Marque to be among the top 25 engineering firms in the region.
