The Great Lakes Computer Team

Any company is only as good as the team members who make it up.

Here are just a few of the real people in Northeast Ohio who stand to assist you with your computer and IT service needs:

David Doucette

Vice President, Operations

We are proud to say that Dave served our country for 8 years in the US Army, obtaining a rank of Sergeant with several overseas deployments. Though he began at GLC as a Help Desk engineer in 1998 (making him one of our longest tenured employees), Dave is an integral part of the Operations group across various levels, where he currently leads as Operations Manager. In this position, Dave is responsible for all service delivery functions within GLC, helping us to deliver results to our clients.

Debbie Tsiros

Accounting Manager

Debbie has delivered hard work and excellence ever since joining the GLC Accounting Department in 2003, becoming Accounting Manager in 2012. Her motto is “whatever it takes to make it work” since every day brings new challenges and solutions to be found. Though she loves accounting (finding it as entertaining as doing a crossword puzzle she says), she also enjoys spending time with family and friends, walking and hiking, reading and playing games, and going for rides in her husband’s sports cars.

Gerri Kelovsky

Accounting Assistant

Bringing with her 20 years of office experience, Gerri has worked in GLC’s Accounting Department since 2014, working closely with both customers and vendors. Outside of work, she enjoys hanging with friends and family, watching movies, dancing, working out at the gym and attending her son’s drum performances. Some of her favorite things include sunsets, wine, Mickey Mouse and anything purple.

Mandy Martinez

Service Manager

When Mandy joined Great Lakes in 2014, she began as a Contract Administrator. She didn’t waste any time and quickly moved through the ranks to her current position. Mandy oversees the Dispatch Department, all local and overseas customer relations, talent acquisition and logistical aspects of our Maintenance Department. However, adventure is Mandy’s true calling. She has gone from parasailing and swimming with dolphins in the Caribbean to touring European castles and everything in between.

James Shuster

Help Desk Supervisor

After attending Lorain County Community College, Jim started at GLC in 2005 as a Help Desk Technician. He’s grown to become quite an invaluable addition to the Help Desk team over the years, receiving the nickname “Ol’ Reliable”. He’s a great technician and is truly a wizard with our customers. As the old saying goes, “Beware of the quiet ones.”

Steve Mihalic

Network Engineer

With over 15 years of IT Customer Support experience, Steve started at GLC in 2017 as a Network Engineer. His ability to work in a larger environment, maintain all the servers, and take care of all the workstations almost single handedly is a testament to his specific skill set. He graduated from Valley Forge High School and TTI, and always brings a willingness to help in any situation, a wide variety of knowledge and a smile.

managed it service

Adam Weeks

Field Manager

Adam is the “new guy on the block”.  But just because he’s the youngster, (he started with GLC in early 2019), don’t underestimate his powers.  Adam is a Network Engineer with over 15 years in the field, he has extensive experience with networking and is a VMware Certified Professional (VCP-DCV6).  Throughout his career he has gained a lot of knowledge in the many areas of IT by learning hands-on.

Joining Great Lakes in 1999, Gary is our Central/Southern Ohio Senior Field Engineer. He brings with him decades of experience in the computer industry and has established excellent relationships with his customers.

Lee Eller

Senior Network Engineer

Lee (or as we like to call him, “Elder” Eller) was GLC’s first hire back in 1987, starting off building systems as an engineer. Over the years, he has tried on many company hats, including running the Field Services Division, but he is truly a technician at heart, which is why Lee is now our Senior Network Engineer.

managed it service

Dan Ondercin

Senior Field Engineer

Servicing all of Northeastern Ohio for GLC since 2000, Dan possesses an exceptional understanding of the equipment he repairs and enjoys sharing his knowledge and mentoring our growing team. Dan lives life to the fullest when he’s not at work, spending his time golfing, fishing and boating on Lake Erie, and performing with his band.

managed it service

John Semonin

Senior Field Engineer

John is our Akron and Canton area Senior Field Engineer. Since teaming up with Great Lakes in 2006, he has built enduring relationships with his customers, by always taking a moment after his repairs to chat and joke along with them and brighten their day a little. When John has time to unwind, he enjoys his vintage train collection and time with family.

Ryan Cameron

Help Desk Engineer

One of our newer members of the team, Ryan has immersed himself in nearly all aspects of IT for the past 25 years. He must have started working in IT when he was 4 years old!! But he seriously enjoys the problem-solving and troubleshooting aspect of working at the help desk, along with the changing issues and challenges every day presents.

managed it service

Rick Wackerly

Senior Sales Executive

Rick was recruited to join the GLC Sales team in 2012. At the time, GLC needed strong sales assistance and Rick previously owned and operated a moving company for 35 years, which means he was out there working on a truck every day! Anyone that can do that, plus maintain positive customer relations, was someone we wanted. Rick brings his charm, wit and “gift of gab” to every meeting and he is still keeping his customers happy after all these years.

Jamie Slack Image

Jamie Slack


Just because you’re new doesn’t mean you’re a “newbie”. Joining the Great Lakes Team with over 15 years of office experience, Jamie was fully equipped to fill the role as our dispatcher. She has great communication skills and enjoys working directly with customers and vendors daily to ensure quality service. Outside of work she enjoys a good book or movie, nature walks and spending quality time with friends and family.


Logan Homler

Support Engineer

Logan joined the Great Lakes team in early 2020 and has worked in both the dispatch and help desk departments. Even as a young lad, Logan grew up around the IT environment and has always been technically inclined, even offering his help to the IT administrator at his high school. I know… he’s one of those “smart guys”! He’s currently pursuing a degree in Cyber Security at Lorain County Community College and looks forward to bringing his diverse skillset to the help desk.


Ben Morton

Network Engineer

Ben has been working in the IT Field for over 10 years now . He started his career before he even graduated from High School. Ben is a natural technician and loves nearly every aspect of IT from troubleshooting problems to making people smile when he resolves their issue. He is active in his church (Cross community Church in Elyria) and even helps them in a tech advisory role. In his free time Ben enjoys playing board games, videos games (the Legend of Zelda series is an all-time favorite) and spending time outside with friends and family.

David Ross Jr

David Ross

Network Engineer

David has been working in the IT industry since the original 8088 chip was introduced to the public, which was quite some time ago. Throughout the years, working in IT, David has done almost everything from building computers, setting up networks, installing servers and working with phone systems both physical and cloud. Throughout his journey, he has learned a lot from the many people he has worked with. However, David is not done yet and still loves learning about the new technology that comes out, almost daily it seems. When he is not messing around with technology, David loves to cook with his wife and travel with her to new places.

He has held multiple positions at GLC including Large Account Sales, Sales Manager, VP of Operations, and now serves as President. Although he oversees all operations, Bob’s primary focus is in the areas of sales development, strategic direction, government sales and large account management.
