I am an Associate in the firm’s Wills and Estates, and Estate Litigation practice groups.

My practice primarily focuses on helping clients navigate some of life’s most challenging moments, whether through estate planning, estate administration, or resolving complex estate disputes. I am committed to offering clients clarity and proactive communication throughout the process.

I earned a Juris Doctor from Thompson Rivers University in 2024 and was called to the Ontario Bar in June 2025.

Before joining Mann Lawyers, I articled with the Ministry of the Attorney General at the Crown Attorney’s office, gaining valuable experience in litigation and advocacy.

During law school, I participated in several community-based programs to expand access to justice and strengthen my commitment to engaging meaningfully with the community.

Prior to law school, I worked as a paralegal in Calgary for four years, predominantly in wills and estates. I hold a Bachelor of Arts in Law and Psychology from Carleton University and a Legal Assistant Diploma from Bow Valley College.

I am also a member of the County of Lanark Law Association.

Outside of the office, I enjoy spending time outdoors, exploring the culinary scene, and competing in just about anything, from sports to boardgames.
