Karina is an Olympic bronze medalist and retired professional athlete who has the distinguished honor of being one of the longest serving soccer players in Canadian national team history. With a prestigious career that spanned almost 18 years at the international level, she participated in 5 FIFA World Cups and two Olympic Games, winning an Olympic medal in London 2012. These accomplishments were among the reasons why Karina was inducted into Canada Soccer Hall of Fame.

Since retiring as a player in 2015, Karina has been named UNICEF Ambassador, a FIFA Legend and founded the Karina LeBlanc foundation, a charity that empowers young women to find their inner greatness and purpose. In 2018, Karina was named an Honorary Captain of the Royal Canadian Navy and in 2022, appointed to the Order of Canada.

In November 2021, Karina started her new role as General Manager of the Portland Thorns and has since added the role of President of Thorns Operation to her name, after helping her team win the NWSL Championship in her first full season in 2022. She was the first African-American and first former player in the NWSL history to be named General Manager as well as being the only person to win a championship as a player and a General Manager. Her goal is to create new pathways for current and former players while showing the power of football (soccer) for positive change. Prior to this, Karina held the position of Head of Women's Football (Soccer) for CONCACAF and its 41 countries, where she helped lead the growth of the women's game in the region and was instrumental in developing and launching its first ever Women’s Football strategy.
