In 1980, Mark Brynteson received his Bachelor of Science Degree in Biochemistry and his Juris Doctorate in 1989. After he graduated from law school, he formed a law firm with two colleagues, now practicing for over 25 years. Today, Mark is a successful personal injury and transactional lawyer, as well as a professional businessman. His primary areas of litigation practice area medical negligence, wrongful death, and personal injury.

Beginning his career in the Tidewater area of Virginia, Mark quickly became one of their most outstanding trial lawyers, acting as a key member of a litigation team during his first year of practice. The team went on to win $5 million on a wrongful death verdict in the Chesapeake Circuit Court. Since then, Mark has achieved successful results for his clients and has won a combined $30 million dollars fighting for others.

When Mark has time, he is strongly representing not-for-profit organizations, even becoming the CEO and acting CFO of two large multi-million dollar NFPs for nearly a decade. One of the NFPs operated two radio stations: six HUD 202 retirement centers and a K-12 school. The other NFP aired weekly TV and radio shows through multiple media channels. Always thinking about the customers, Mark implemented risk management programs in order to promote a safe environment. He also reduced annual insurance premiums by $25,000.

Mark is very well-versed in the real estate facet, working extensively with buyers and sellers of residential property. Real estate transactions can be complex and confusing, so he makes sure to devote his undivided attention to his clients and that all details are accounted for when it comes to transactions. When you work with Mark, he promptly responds to calls and emails.

Mark will also work with you as you begin your estate planning to ensure you are properly preparing a will or trust. He believes in education-based planning, so his goal is to inform people of their planning options and help them make quality, informed decisions.

Very nice people! Brittany was amazing! She was able to get my mother's lien for her hospital bills negotiated down to a very reasonable price. She was with us every step of the way. My mother got her settlement from her car accident within 3 weeks of hiring them. Highly recommended!
