2023-2024 Executive Committee



Dr. Matthew Thiessen, President

Matthew (He/Him) is a PGY-4 Rheumatology resident. He is Winnipeg born and raised, and completed his undergraduate and medical training here in Manitoba. He has served on PARIM the past two years as Social and Wellness Committee chair and as a medicine group representative. He is excited to take on the challenges and opportunities of the PARIM presidency this year.
Outside of work Matthew is a proud nerd, with a passion for board games, choral singing, sneakers, novels, video games, and baking. He is a world champion in two games at the World Boardgaming Championships, which he competes in annually. Check out his amazing community choir Horizon, where he sings Baritone.
Matthew has been a strong advocate for systemic and cultural changes to improve resident wellness and will continue that work in his new role. However, he is most excited to champion PARIM’s focus on Equity, Diversity, Inclusion, and Decolonization as we work to dismantle structural inequity and decrease discrimination. He looks forward to being an unwavering advocate for resident rights. He can’t wait to hear from residents what their priorities are for this year, so please reach out!
