Executive Management


Dennis Cohan, CEO

Dennis first established the company as a specialized general contractor in 1987, and soon thereafter discovered a gap in the provision of fire barrier management services within healthcare environments. In response, he launched PREVENT to provide facility owners and managers with accurate inspection and repair of their fire and life safety systems to maintain compliance with the fire code. Under his guidance, the company has become the recognized leader in the industry, and has grown beyond the original office in Northern California to include regional offices and service areas throughout the US.

Educated at Chico State University, Dennis holds bachelor’s degrees in biology and chemistry.  As CEO, his focus is on ensuring PREVENT continues to deliver the highest quality fire barrier management and code compliance services while envisioning the next stage of the company’s development. He is committed to “doing what the best company would do,” and empowers the staff to make responsible choices in alignment with that mandate. As both an early founder and expert in the fire/life safety industry, Dennis represents the company and speaks at numerous events nationwide.

In 2012, he and his wife relocated to Arizona, where Dennis enjoys golfing, hiking, and 4×4 Jeep exploring in the desert.

Jodi Clem, President

Named President in early 2018, Jodi has been with PREVENT for 21 years, serving in nearly every capacity since joining the firm.  A thought leader and industry subject matter expert, she is regarded as an authority in firestopping, fire dampers, and fire safety code.

A past President of FCIA, Jodi holds certifications through ASHE, NADCA, Hilti and STI, and is active in those organizations as well as TAHFM, WSSHE, CSHE and CASHE. She regularly delivers keynote and technical subject lectures, teaching safety techniques and code requirements to facility owners, directors, and engineers.

Jodi is responsible for the US operations of PREVENT. She is focused on developing new markets while serving as chief technical and code expert and managing the national sales team and business development program. Major accounts she personally manages include Stanford, Cedars Sinai, UC David Medical Center, John Muir Health and Kaiser Permanente.

Jodi earned her BS in Kinesiology from California State Sacramento, and completed certification in NFPA 80 Inspection of Fire Door Assemblies in Healthcare Occupancies, Association of Builders and Contractors Leadership Training, Dale Carnegie Sales Training, and Hilti Specialty Contractor Training.

A Bay area local, Jodi lives in northern California with her significant other, a golden Labrador and a moody 7-pound Chihuahua. She enjoys golf, kayaking and hiking, and is working on visiting all the US National Parks. The family spends weekends in the Lake Tahoe area enjoying outdoor pursuits.
