Sam W. Stowell


Grandson of Frank H. Stowell, Sr., the originator of the company, Sam started working for the firm, then run by his uncle, Frank H. Stowell, Jr., in 1974 as an apprentice carpenter. Inspired by stories of the firm’s past and the integrity that his uncle demonstrated in everything he did, Sam gradually took on increasing responsibility, first in the field and then in company management.

After his uncle’s death, Sam ran the day to day operations on his own for over twenty years, until earlier this year.  At that time, he handed over the day to day operations to Chuck Wiesneth who took over as President.

Sam continues to oversee the healthcare project team and still finds time to work with customers and vendors to build that business. It’s those relationships, and those with his staff, that Sam values most. That the healthcare projects that the company completes help so many to recover from debilitating medical conditions, is something Sam finds very rewarding.

Sam completed the college degree at Northwestern’s University College in 2002 that he started at Vanderbilt University

Chuck Wiesneth


Chuck is President of Frank H. Stowell & Sons. Despite having a Master of Science in Education (on top of an Associate Degree in Applied Science in Construction Technology and a Bachelor’s Degree in construction management), Chuck started with the company as a carpenter in 1988. It was no surprise that he worked his way up, first to carpenter foreman, then to the superintendent and then to project management, before becoming Vice President and, finally, President.

Chuck continues to seek improvement in his own skills and in what we can provide our customers. On top of estimating and overseeing a number of projects, Chuck schedules all manpower and manages the day to day management with a team of experienced project managers, estimators and support staff.

Chuck appreciates the company’s philosophy of being honest and fair. He sees this as the reason for the high level of morale, spirit and community in the workplace and the commitment to producing a final product of high quality.

Brian Fuller

Project Manager

Brian Fuller is a Project Manager at Frank H. Stowell & Sons.  Brian joined Stowell in May of 2015, bringing with him three decades of commercial and institutional experience in managing construction projects.

Brian’s expertise came from starting his own company in his 20’s and taking on ever more challenging projects such as custom homes and high-end restaurants. Known for quality construction and calmness under stress led to Brian running school renovation projects with their unique challenges.

It was a natural progression for Brian to be recognized as a valuable resource by Northwestern University, at both their campuses (Evanston and downtown Chicago).  His team took on the full range of mid-sized remodeling projects: American Disability Act (ADA) additions, fraternity and sorority renovations (including total gutting), elevator construction, classroom buildouts (including technology), and restaurant build-outs.

Stowell has benefited from the addition of Brian and his team of skilled tradesmen who help us to meet all manner of needs that a major college with an international reputation has.  Remarkably, Brian, over the last twenty years, oversaw work in just about every building on both campuses.  Even more impressive is that Brian has maintained an excellent rapport with all his clients, a rapport based on his dedicated professionalism.
