Meet the Founders
We're Trevor Seay and Garrett Cox, the founders of Cornerstone Payments.
We've both spent years working with small business owners - and we've seen firsthand how confusing and expensive payment processing can be when you're dealing with the wrong provider.
Our goal was simple:
Make payment processing straightforward, affordable, and personal.
We partner directly with reputable processors like North, EPX, and PaymentsHub, giving our clients secure, transparent solutions with responsive local support. When you call us, you're talking to a real person - not a call center.
About
Local Roots. Professional Service. Real People.
At Cornerstone Payments, we believe small business deserves big-league support.
We’re a locally owned merchant services provider helping business owners and professionals simplify how they get paid — without the headaches, hidden fees, or runaround you get from national processors.
What started as a small consulting partnership between two local entrepreneurs has grown into a trusted payments partner for businesses across the Carolinas. We’re proud to offer the same secure, modern payment technology used by major brands — but delivered with the personal touch only a local team can provide.
The Cornerstone Payments Team
Trevor Seay
Chief Executive Officer (CEO)
An entrepreneur at heart, Trevor has built and scaled businesses before launching Cornerstone Payments. His focus now is helping other business owners do the same - leveraging the right technology and payment systems to simplify cash flow and unlock growth.
When he’s not working with clients, you’ll find Trevor on the lake with his wife and daughter or on the golf course with friends.
Garrett Cox
Chief Operating Officer (COO)
A builder at heart, Garrett has spent his career turning vision and hard work into lasting results. With experience managing projects and client relationships across the Carolinas, he’s known for integrity, reliability, and hands-on leadership. Today, he helps merchants find payment solutions that fit their needs and budgets.
Outside of work, Garrett enjoys time with his wife and two boys - his greatest motivation in everything he does.
Mark Seay
Sales Agent
With over 30 years of experience owning and operating insurance agencies across the Charlotte metro area, Mark has built a career on helping people save money and receive top-notch service. An expert in customer relations, he takes pride in finding payment solutions that truly fit each merchant’s needs and budget.
When he’s not working with clients, Mark enjoys spending time with his family or catching a live band around Gaston County.
Our Mission & Promise
To help hardworking local business owners and professionals save money, simplify payments, and focus more on what they do best - running their business - while we handle the technology behind the scenes.
We don't believe in "set it and forget it" merchant accounts.
When you work with Cornerstone Payments, you're not just getting a processor - you're getting a partner who's invested in your success.
