Our installers and service technicians are trained by the Electronic Security Associations National Training program, and they attend continuous in-house and manufacturers training. A well trained technician ensures each client the very best in trouble-free installation and service.

For the past 40 years, Scott has been a dedicated professional in the life safety industry, with a strong commitment to community service and raising awareness. He has previously served as the Vice President of the Northern Region of NJELSA and currently holds leadership roles as the President of the Rotary Club of the Caldwell’s and Chief of the North Caldwell Fire Department.

Scott’s passion for the field was sparked as a child, when he became captivated by the TV show Emergency! A fascination that would eventually shape his entire career. Today, he credits his entrepreneurial drive and deep desire to help others as the key factors behind his enduring success.

From its humble beginnings in Verona, New Jersey, Scott has grown SMS Security Systems into a respected and thriving business.

Additionally, Scott has shared his expertise by teaching security and fire alarm systems at the Essex County Police Academy and local fire departments.

Never one to rest on his laurels, Scott continues to push SMS Security Systems to new heights.
