William Quirion


I was born and raised in Maine, but I am now glad to be a citizen of South Carolina. I grew up spending every summer in New Hampshire on Lake Winnipesaukee, which is where you can probably find me if I’m not in South Carolina.

I attended Liberty University for my undergraduate degree where I obtained my Bachelor of Science in Business Administration with focuses in financial planning and economics with magna cum laude distinction. After graduating in December 2013, I worked for a small financial advising firm in my home state of Maine.

During my time in undergrad, I decided to go to law school because of my passion to learn and a desire to solve complex legal issues in the fields of Estate Planning and Financial Planning. I attended Liberty University School of Law in the fall of 2014 and graduated in May 2017.

During my work as a financial advisor, as an attorney, and throughout life in general, I have seen many unfortunate estate and business planning mistakes or simply suboptimal planning. From small businesses failing because of a lack of a proper succession plan to dramatic and expensive estate battles because of poor planning, it never ceases to amaze me how proper planning can make such a difference. I have a strong passion to help people and businesses best plan for their future.

After passing the bar exam, I started a solo practice firm in Maine where I worked for a year and a half before deciding to start AVP Law with Dylan Lingerfelt. Dylan and I became good friends during our three years in law school. I have never met a more intelligent and pleasant person to work with. We are excited to provide individuals and families with top tier legal services and look forward to maintaining a lifelong relationship with all our clients.  

I am licensed to practice law in South Carolina and Maine. Additionally, I hold a Certified Financial Planner designation (CFP®).
