Boutique CPA-led accounting & advisory for established Lancaster County businesses
Growing businesses face decisions that can make or break their next stage. We give you CPA-led numbers and insight to make them with confidence, through ongoing monthly support or a one-time project tailored to your business.
Growth brings bigger, faster decisions, and the cost of getting one wrong goes up. If any of these questions sound familiar, we can help you answer them.
Why Conestoga
As your business grows, the decisions get bigger: when to hire, how to price, where to invest. Making them well takes more than accurate records. It takes a CPA who understands your numbers, explains what they mean and helps you plan what’s next.
Who we work with: established small and midsize businesses that have outgrown basic bookkeeping but don’t yet need a full-time controller or CFO.

Meet the President
Before founding Conestoga, Christian spent 6 years at PwC, most recently as a Manager in audit and risk advisory, helping some of the world’s largest companies solve complex financial and operational challenges.
He started Conestoga Advisory Group to bring that same level of expertise to small and midsize businesses, giving owners the insight to make confident decisions as they grow, with every client relationship led by a CPA who knows the business and picks up the phone. The goal is to build relationships that last decades.
Outside the office, Christian serves in the Pennsylvania Army National Guard, including a 2024 deployment to the Horn of Africa, and is a graduate of U.S. Army Ranger School. He lives in Lancaster City with his wife and their Labrador retriever.
We learn about your business, your current accounting processes and your business goals.
We recommend the right services and provide a clear, fixed-fee engagement proposal.
We set up access, assess your existing records, identify any cleanup needs and agree on deliverables.
We provide recurring accounting, reporting and advisory services as outlined in your engagement.
Note on cleanup: if your books need catch-up or cleanup before monthly work begins, we’ll scope and price it separately as a one-time project, so you know the cost up front.
