Joseph S. Marquette

Chief Executive Officer

As the founder of Accellis Technology Group, my journey has been driven by the goal of fostering a team culture that thrives on innovation and excellence. At Accellis, we’re not just a team but a community of A-players, constantly challenging ourselves to create new and better solutions for our clients and our industry.

Our success is rooted in a shared commitment to having a positive impact on the communities we serve, embracing challenges as opportunities for growth, and staying ahead of the technological curve. My educational background from the University of Illinois laid the foundation, but it’s the collective wisdom and drive of our team that propels Accellis forward.

Looking ahead, my vision for Accellis includes expanding our geographic footprint, diversifying our service offerings, and continuing to surround ourselves with individuals who are not only smart and passionate but also dedicated to our mission of excellence. We believe in continuous improvement – what we are today is a step ahead of where we were six months ago, and six months from now, we’ll be even stronger. Join us on this journey as we redefine the standard in professional IT services.

He received the President’s Education Award for Outstanding Academic Achievement in 2002 and is Co-Founder of a real estate investment & construction management company.

Thomas Fazio

Director of Cybersecurity

Tom Fazio was CEO of his consulting business Big Mountain Technology located in Chagrin Falls, Ohio. In a ten-year span since its inception, he grew the business to more than a dozen clients, with monthly MSP contracts. He employed up to 4 full-time technicians.

From his beginnings in IT in 1996, Tom has progressed rapidly from designing and setting up his first Novell server on a BNC file-sharing network. In 1998 Tom joined Netnowledge Inc (later re-named Thinsolutions), as a senior technician, where he helped the company change direction from traditional consulting to an Application Service Provider (ASP).

In 2000, Tom joined Capstone Realty Advisors as Chief Technology Officer (CTO), where he remained for eight years, eventually providing – with the assistance of just one colleague – total IT support for 16 servers, six branch offices and a total of 85 employees.

In 2008 Capstone was closed down by its new owner PNC. Tom decided to use his experience and expertise, supported by his severance package, to set up and build his own consulting business. Big Mountain Technology was the eminently successful result before merging with Accellis.

Tom has an in-depth understanding of program and business process trends and issues, can identify the practical implications of new technologies, and can relate system capabilities to business and program goals.

When not working, Tom enjoys spending time with his family in Chagrin Falls and listening to his extensive collection of music.
