Vincent Sliwoski, Attorney

"Whatever you can do, or dream you can do, begin it. Boldness has genius, power, and magic in it. Begin it now."
Vincent Sliwoski

Vince advises a wide variety of businesses on transactions and disputes, including intellectual property and real estate matters. He has particular expertise in music and trademark law and is a leading practitioner in Oregon’s fast evolving cannabis industry. Vince is not afraid to go the distance for his clients. He has tried cases in four Oregon counties and conducted numerous arbitrations and mediations.

Vince graduated from Lewis and Clark Law School, where he now teaches Cannabis Law & Policy as an adjunct professor. In his student days, Vince was inducted into the Cornelius Honor Society for scholarship, leadership and service. He was also champion of the Phillip C. Jessup International Law Mid-Atlantic Competition and won best U.S. Brief in 2009. 

Before practicing law, Vince lived in Japan and worked and traveled extensively throughout Asia, Europe and the Americas— including 2,000 miles by canoe through the Canadian arctic. He is fluent in Spanish and speaks basic Japanese. While living in New York City, Vince worked with a boutique IT firm supporting Bob Dylan, Lou Reed and other artists. 

As an active supporter of Oregon’s creative culture, Vince has served as general counsel to the Pickathon Music Festival since 2011, and he is President of the Hollywood Theatre Board of Directors. He is also active with Oregon Volunteer Lawyers for the Arts and writes for the Portland Mercury. On weekends, Vince enjoys exploring the beauty of the Pacific Northwest with his wife and friends.
