Mario Pizzamiglio, Esq., CPA, CFP®
President & CEO
Mario Pizzamiglio is the founder of Ardent Guardian PC. He’s been helping small business owners grow their businesses for over 15 years. His primary areas of practice are business advisory, asset protection, and advanced estate planning techniques. He is admitted to practice law in Virginia.
He is a member of the American Academy of Attorney-CPAs, the Virginia State Bar, the American Institute of Certified Public Accountants, and the National Veteran-Owned Business Association. When he’s not in the office, you can usually find him tinkering around on his ’69 Ford Torino, hiking with his wife and kids, or sending out “Go Army, Beat Navy” emails to all Ardent Guardian’s clients (much to Shelby’s chagrin).
Shelby Crow
Executive Officer
If there’s a bright center of the Ardent Guardian universe, it’s Shelby Crow. As the firm’s XO, she oversees and manages all aspects of business operations. (But her hardest job, by far, is trying to keep Mario in line.) She has extensive experience leading client engagement across multiple professional fields and is the primary point of contact for Ardent Guardian’s clients. She is currently adding to her professional acumen by completing a paralegal certification at the University of Texas, Austin and has her sights set on law school in the near future.
During her off time, you can usually find her outdoors on horseback, at the range, or enjoying time with her daughter. She’s a self-proclaimed ‘adrenaline junkie’ and has been known to jump out of perfectly good airplanes from time to time. Shelby is also fluent in both American Sign Language and English Sign Language, and she is a staunch advocate for the deaf and hard-of-hearing community. In short…she’s a Rockstar!

Why Choose Ardent Guardian?

We’re cool, we’re hip, and we provide all-in-one solutions that can help you continue to grow.
Licensed Attorney, CPA, and Financial Planner
Unlike most CPA’s or accounting firms, we are licensed in both the financial and legal sector as an attorney, CPA, and Certified Financial Planner. As an influencer, content creator, small business or solo entrepreneur, having a CPA, financial planner, and attorney handling your personal, financial and business needs gives you an upper-hand on many fronts. From tax preparation to estate planning and contractual legal agreements, we can help you with most situations that require financial and/or legal help. Don’t let these fancy titles confuse you though, we’re also pretty cool.
All-In-One White Glove Service
Having a go to person for your financial, accounting, and legal needs can bring a lot of value to your business. But what probably brings you even more value, is having a team that truly gives hands-on service and goes above and beyond for your business. We have a small client base for a reason – so we give maximum attention to every one of our clients.
