Vincent Sliwoski, Attorney

"He is outstanding to work with, very collaborative and practical." – Chambers USA
Vincent Sliwoski

Vince is a business lawyer, problem solver and dealmaker. His clients run the gamut from individual investors and entrepreneurs to widely held domestic and international corporations. Vince is Harris Bricken’s managing partner, and he has won accolades from Super Lawyers and Chambers USA for his work.

Vince pushes for efficient and optimal client results in every transaction. He has particular expertise in business/corporate, commercial real estate and intellectual property law. Vince’s advice is guided by a heightened awareness of all possible outcomes: in his litigating days, he tried cases in four Oregon counties and conducted numerous arbitrations and mediations.

Vince is also a leading practitioner in Oregon’s rapidly evolving cannabis and psychedelics industries. He publishes our law firm’s award-winning Canna Law Blog and Psychedelics Law Blog and regularly confers with the Oregon Liquor and Cannabis Commission on agency rules and policy. Vince has been hired by the Oregon State Bar and private parties as an expert witness in several cannabis-related disputes. He also taught one of the first law school courses nationwide on Cannabis Law & Policy, from 2017 to 2021.

Vince actively supports Oregon’s creative and non-profit cultures. He serves as general counsel to some of the state’s signature events, including the Pickathon Music Festival and the Waterfront Blues Festival. He is a former columnist for the Portland Mercury and past President of the Hollywood Theatre’s Board of Directors.

On weekends, Vince enjoys spending time with his wife and kids, hanging out with friends, and sleeping outside whenever possible.

What clients have to say about Vince

“We tremendously value our relationship with Vince and team at Harris Bricken. They are a trusted partner we rely on each and every day. From M&A deal-making to cannabis licensing and beyond they are exceptionally competent across legal specialties and jurisdictions. Beyond this they bring a low-ego and collaborative approach that blends well with our company values and culture.”

David Lannon, CEO Tumalo Industries, Retired EVP | Whole Foods Market

“Legal stuff is always scary. And I’ve had to play offense a couple times, begrudgingly. To have Vince have my back? It made things a lot less prickly. He quickly walked me through my options, and was refreshingly consistent in his communications, timing and billing. I’ve been lucky to stay out of the legal side of things my whole career, thankfully. When things went a little wrong, Vince quickly made things right. And he was friendly. The more lawyers I meet, the less I like them. Vince broke that pattern for me. Thank you, Sir!”

Aaron Draplin, Founder | Draplin Design Co

Vince Sliwoski has been an invaluable asset to Waterfront Blues Festival and Fuller Events over the past several years. His knowledge, professionalism, clear communication and understanding of our unique industry truly sets him apart. He’s one of the first people we call when we have a question or concern. Time after time he provides us with excellent guidance and timely advice. We’d absolutely recommend Vince and the team at Harris Bricken.”

 Christina and Tyler Fuller, Co-owners Waterfront Blues Festival and Fuller Events

“When we started the process of building a ‘seed to sale’ cannabis company in Oregon, we saw the need for expert legal counsel.  The cannabis sector is fraught with potential peril at every turn, and we wanted the best legal advice we could find.  After talking to several firms and individuals, we feel extremely fortunate to have chosen Harris Bricken and Vince Sliwoski as our legal counsel.

Harris Bricken is the equivalent of a ‘seed to sale’ law firm in the cannabis space, in that they have helped us through virtually every step of the legalization process.  Vince helped us create Redbarn Cannabis, complete with our 12 OLCC MJ licenses and multiple companies.  He has guided us with setting up our companies, investor offerings and legal documentation, and has helped us with countless legal issues, including real estate transactions, compliance questions, and state/local regulation issues.  In fact, everyone we’ve worked with at HB is an expert in their space.

When faced with a legal issue or decision, my first call is always to Vince.  He understands the complexities of the industry, and has never failed to provide expert, relevant, and valuable counsel.  In our opinion, you cannot make a better choice.  Vince Sliwoski and the Harris Bricken team has helped us build Redbarn Cannabis into a successful thriving enterprise that benefits the state of Oregon, the communities we serve, our employees and our customers.”

 Tony Theiss, CEO and Co-Founder, Redbarn Cannabis

“I am pleased to endorse Harris Bricken as one of the first, and finest, law firms to specialize on assisting the new state-legal marijuana industry. NORML and many of our members and affiliates have worked with Hilary Bricken, Vince Sliwoski and this pioneering firm on everything from public interest litigation to general business and compliance matters over the years.”

Keith Stroup, Founder and Chief Legal Counsel | NORML 

“Vince Sliwoski and Harris Bricken have been nothing but an asset to our company throughout the years. Whether it’s navigating regulatory questions, employee disputes, trademarking, licensing or just general business transactions, Vince and co are always there to help navigate us through. Especially, in an industry with so much red tape, having a law firm that can tackle all of it with you is invaluable.”

Brent Stewart, Co-Founder and General Manager | Gnome Grown

“Working with VinceSliwoski was extremely helpful as our company set out to establish our recreational licenses in the Oregon cannabis industry. He helped us navigate the intricate waters of licensing for a public cannabis company and clearly explained what process would entail. We came to trust Vince’s expert opinion and would happily refer anyone looking to establish their cannabis presence in Oregon.”

Kiran Sidhu, CEO & Director | Halo

Vince and the team at Harris Bricken have been a go-to resource as our organization has changed and grown. We’ve relied on the team’s expertise for advice spanning from organizational structure to packaging requirements. They are always responsive, thorough, and thoughtful giving us the peace of mind that we are moving forward with compliant and considered decisions in an environment that is ever evolving and exceedingly challenging to navigate.

– Victoria Pustynsky, Founder & CEO | Aurora Elixirs

“I am impressed with this law firm! They answered all my questions regarding business laws and regulations in Oregon and they have helped me with a variety of legal issues in a timely fashion, while always clearly communicating with us throughout the process. They also redirected me to other quality people for my business needs. Everyone I worked with at Harris Bricken is an expert in their field, and I was in good hands throughout my legal representation.”

Zale Schoenborn, Founder and CEO | Pickathon
