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.

Chief Operating Officer

I’m Brian Guscott, the COO at Accellis. For nearly the last 30 years, I’ve had the opportunity and privilege to help many different organizations implement, maintain, and optimize their technology solutions, from hardware and software to networks and security.

Because technology affects all aspects of business, I’ve witnessed how it can help various sectors and fields. I’m passionate about the intersection of technology, people, and processes that combine and interact to create amazing solutions that enhance outcomes and results for clients, their workers, and their stakeholders. I think that technology is not just a tool, but a driver of innovation and change.

With a mindset of continual improvement, I work with the rest of the Accellis team to drive our own operational maturity, facilitate the development of emerging technologies, and deliver exceptional value to our clients, communities, and people.
