If you're looking for a full-service, trustworthy, expert accounting firm, you found it! Eight years ago, I started a business so that I could share my expertise with others. Little did I know running a marketing business also meant bookkeeping, managing payroll, filing taxes, etc. Truth be told, I'm pretty good with words, but not at all with numbers. I routinely make mistakes and find accounting tasks painful. I was referred to GWCPAs by one of their former employees (that told me everything I needed to know). Over time, I continue to experience first-hand GWCPA's expertise, patience, and support from every staff member I work with. In the early years, GWCPAs helped me with basic tasks like monthly bookkeeping. We'd have quarterly check-ins to evaluate how things were going financially and they'd make recommendations on adjustments and direction. After a few successful years, GWCPAs recommended I transition from an LLC to an S CORP and they guided me through every step of the process. Today, I trust all of my accounting needs to GWCPAs: bi-weekly payroll, monthly invoicing, annual reporting and filings, you name it they do it... right! The ability to offload these tasks frees up my bandwidth to focus on growing my business but, moreover, the ability to trust that these activities are performed correctly gives me priceless peace of mind. I regularly recommend GWCPAs to my network. Kate McLean, Written LLC - Mechanicsville, MD
William Pope Travers was one of the very first clients of Paul Garbelman in the late 1940s, when he opened Popey’s Tavern in District Heights and needed professional guidance. Now Popey’s descendants are clients in force – as the branches of the family expand and the myriad businesses and lives evolve, we always turn to GWCPAs for financial guidance and clarity. As clients we know that this firm will always respond respectfully and knowledgably, that this firm is on our side and up to date in all law changes, and that this firm will never veer from the honest and ethical path. They have our complete trust and respect, and we feel respected in turn. Janet Travers, Travers Families and Related Businesses - Owings, MD
"But a good CPA is expensive!" You know one way to really quickly 3x your business? Hire a good CPA. Not HR Block or TurboTax. I mean someone really worth their salt. Not only will they pay for themselves in the money they keep in your pocket on tax day, but all the additional revenue and decreased stress can be invested back into the business for growth. Always grateful for my guy Barrett Young. John Flagg, Rebuild Stronger LLC - Oxford, NC
We have been with Garbelman Winslow ‐‐ now GWCPA ‐‐ for over 40 years. Why? Because the courtesy, personal attention, and professional service we have received over the years have been consistently top‐notch. From the preparation and submission of tax returns to the prompt and comprehensive responses to our random tax‐related questions, we have always been pleased. Samantha Bowling, our longstanding CPA and now Managing Partner, somehow manages to make the intimidating (to us) subject of taxes just another mildly unpleasant task. Whatever the context, we are confident that we have the assistance we need to proceed with confidence. We'll never look forward to taxes, but we'll always look forward to dealing with GWCPA. Paul and Marianne Smith - Bethany Beach, DE
I would definitely recommend GWCPA, in particular Samantha Bowling. Their team is extremely knowledgeable, helpful, informatve and professional. We are a family‐owned business with a lot of moving parts. We find GWCPA to be an integral part of our business. Marietou does our bookkeeping and assists Samantha in tax management, she is also top notch! PJ Martini, Martini and Associates - Annapolis, MD
GWCPA's unwavering commitment to giving back, relentless pursuit of innovation, and unparalleled dedication to nurturing the next generation of talent sets a shining example for accounting firms everywhere. Rebekah Olson, The MACPA Foundation
