Meet our team

Brian McCarthy

President, Partner

Brian, President and Partner of Open Tier Systems, has been working in the tech industry since 1995, when he started at CompUSA. He recounts this job as his steppingstone into the tech world. After CompUSA, he interned at Merck for two semesters, and upon graduation from high school in 1997, he began working with them full time. After Merck, he worked for a consulting company, and then, in 2006, Open Tier Systems was born. Being the President and part owner of Open Tier, Brian is responsible for overseeing strategic as well as day-to-day operations, meaning he does a little bit of everything. Something that he carries with him as he runs operations day-to-day is what he learned from the Goldman Sachs 10,000 Small Businesses program: “That was a total mindset shift, where I learned to focus more on the business, as opposed to being in it.” As it pertains to his role with Open Tier, what he enjoys most about what he does is solving problems for our clients. He describes it as “being a detective in a lot of ways”. When not helping run the business, Brian enjoys spending time with his children, martial arts, cooking, and working out. 

Rick Carpenter

Vice President, Partner

Rick, Vice President and Partner of Open Tier Systems, had his start in the tech industry in 2002, when he worked for College of William and Mary IT while he was still in school. After graduating, he continued to work for them for six months. Following this, he moved to PA to begin working for Beyond Development, which he started running in 2005. Rick has been Open Tier’s Vice President since January of 2023, when Open Tier and Beyond Development merged. In this role, he oversees the service side of projects, specifically special projects, security, and making sure the help desk is running smoothly. One of Rick’s favorite things about what he does is solving problems. He also finds great satisfaction in acting as our clients’ strategic partner to help them grow and thrive by keeping their costs low and their operations efficient. When not helping clients, Rick loves coaching his children’s youth sports teams, participating on the local school board, volunteering at church, and spending time with family. 

Josh Findlay

Sales Manager

Josh began with Open Tier eight years ago as a Client Services Representative. He is now Open Tier’s Sales Manager. In this role, Josh is responsible for interacting with our clients and nurturing the relationships we have with them. He strives to understand our clients’ struggles and the goals of their business so that we can find them the proper solution for the long term. His favorite thing about what he does with Open Tier is truly maintaining those relationships with our clients. He views these relationships as partnerships, rather than transactions. When Josh is not working, you can find him on the golf course, watching a Philadelphia sporting event, or spending time with his family. 

Deb Kozol

Business Manager

Deb had her start with Open Tier back in January of 2018. She is our Business Manager, so with that, she takes on several tasks, such as bookkeeping, office operations, HR, the hiring and onboarding process of employees, billing and making payment arrangements with clients, collections, and maintaining relationships with our vendors. When it comes to her job, she is passionate about making the culture and environment of the workplace as pleasant as possible, resolving any issues regarding clients’ accounts, and keeping Open Tier in order so that we can continue to grow. While not performing one of the many tasks that she is responsible for, Deb loves to read, garden, immerse herself in art and creative endeavors, and spend time hanging out with her husband and daughter.

Tim Brumbley

Technical Specialist

Tim’s tech experience goes back to 2007, when he worked in a laptop repair business. While working for this business, his main duties were diagnosing issues and repairing the laptops. Therefore, he was mostly working with hardware. He continued hardware repairs in his next job, where he was for eight years, while slowly moving over to service desk related tasks. He worked for Beyond Development for five years, and now with the merger, he has been with Open Tier since January 2023 as one of our Technical Specialists. What Tim enjoys most about what he does for Open Tier is assisting clients in resolving their tech issues. He understands that having computer problems can limit one’s productivity, so getting our clients back up and running is important to him. When Tim is not working, he enjoys spending time with his daughter.
