A trusted advisor first. An accountant second.
From tax planning to long-term business guidance, GRS helps Virginia organizations and professionals navigate financial decisions with clarity, trust, and proactive support.
Built for the people and organizations Virginia depends on.
Different clients. Same principle: relationships first, planning year-round, and a real advisor on the other end of the phone.
Business Owners
Owner-operators navigating growth, hiring, financing, and the financial complexity that comes with scaling a real business.
Healthcare Practices
Physician groups, dental practices, and specialized clinics balancing payroll, cash flow, and the operational realities of patient care.
Nonprofit Organizations
Mission-driven organizations that need disciplined accounting, board-ready reporting, and grant-aware planning.
Individuals & Families
Established professionals and families with multi-source income, planning needs, and questions a basic preparer can't answer.

The strongest accounting relationships are built on trust.
"If I can't help you, I know someone who can."
Our clients don't come to us for forms. They come for judgment, perspective, and a partner who answers the phone. After decades advising Virginia businesses, healthcare practices, and nonprofits, our reputation is built on three things: relationships, referrals, and being genuinely useful.
Organized. Personal. Built for the long term.
Working with GRS feels less like hiring a tax preparer and more like adding a financial partner to your team — calm, structured, and always one conversation away.
We start with a real conversation — your business, your goals, the questions you've been carrying.
A clear, written plan: tax position, reporting cadence, and the financial decisions ahead.
Year-round access to Mark and the team — quarterly reviews, planning conversations, and proactive recommendations.
Monthly close, recurring check-ins, and a relationship that compounds in value over time.
A trusted advisor for Virginia healthcare practices.
Healthcare doesn't run on a normal calendar. Reimbursement cycles, payroll complexity, and partner economics demand an accountant who already speaks the language — and who stays close to the practice all year long.
We work with physician groups, dental practices, specialized clinics, and the professionals who lead them.
- Operational complexity & multi-entity structures
- Cash flow planning across reimbursement cycles
- Payroll, partner comp, and physician productivity models
- Tax strategy that follows clinical and business growth
- Financing, expansion, and acquisition advisory
- Year-round access — not just at filing time
We make working with your accountant feel easier.
Modern tools, organized workflows, and a calm cadence — so the relationship feels high-touch without feeling high-friction.
Get started in a few clicks — secure document collection, no paper shuffling.
Encrypted exchange of documents, statements, and signatures — built into the relationship.
Quarterly reviews and planning conversations on the calendar — not crammed into March.
We surface deadlines, decisions, and opportunities before they become urgent.
The people who work with us tend to stay.
Our growth has been built almost entirely on referrals — clients sending us the people they trust most. That's the only kind of growth that matters to us.
Mark is the first call I make on any major business decision. He's an accountant by license, but a true advisor in practice.
GRS treats our nonprofit like the mission matters as much as the math. We've never felt like a line item.
When we needed an attorney, a banker, and a payroll partner, Mark connected us to all three. That kind of network is rare.
