Chanelle R. Acheson

Harvard-educated and a former Marine Corps officer, Chanelle Acheson brings leadership, intensity, instincts and experience to solving the problems faced by clients. Whether she is leading an internal investigation at a publicly traded corporation, defending a manufacturer in an environmental enforcement action or leading a team representing a financial institution in bet-the-company litigation, Chanelle is a relentless client advocate. 

Chanelle is an effective litigator with practical tactical courtroom experience ranging from the common areas of the law to the more obscure. This broad base of litigation experience is valuable to clients who rely on Chanelle as a trusted advisor when it comes to solving unique problems. She recognizes that client objectives can often be accomplished without lawsuits by instead developing creative solutions to complex and seemingly intractable issues. As a result, she is frequently engaged by companies to respond quickly to unusual legal situations and assemble teams for high-stakes, bellwether litigation.

In the role of litigation team leader, Chanelle is committed to mentoring less-tenured lawyers and providing opportunities for them to acquire practical experience in real situations. By positioning younger team members to develop critical skills and take greater responsibility early in their careers, she not only helps to ensure their preparedness for tomorrow’s challenges but strengthens the teams representing Waller clients today.

From 2005 to 2011, Chanelle served in the United States Marine Corps as a Judge Advocate, presiding as prosecutor in more than 170 cases and conducting first-level administrative review of all criminal convictions within the Eastern Recruiting Region. As a Special Assistant United States Attorney, she prosecuted all misdemeanor crimes committed by civilians aboard the Marine Corps Recruit Depot at Parris Island in federal magistrate court. Additionally, Chanelle served as Ethics Advisor to the Commanding General and as a member of the Environmental Impact Working Group. During her Marine Corps service, Chanelle authored a memorandum that addressed whether certain information available on the Marine Corps Training Information Management System violated federal HIPAA privacy regulations. Following internal circulation of the memo, the Marine Corps initiated a comprehensive review of its information management policies and procedures. Of her numerous accomplishments in the Marine Corps, Chanelle is most proud of having served as Commanding Officer to more than 400 Marines, Sailors and civilians aboard the Marine Corps Recruit Depot at Parris Island.

Up Close

Away from the office, Chanelle enjoys hiking, camping and cheering for her son’s little league team. She holds a black belt in the Marine Corps Martial Arts Program, and she has completed a number of marathons and triathlons. In recent years, four dogs in need of shelter and care have inexplicably turned up on her doorstep and found a home.
