Our Client's Successes
We use Harris Sliwoski on all our international legal matters, including on our international litigation matters. We have over the last few years been involved in a couple big international legal disputes and Harris Sliwoski’s international dispute resolution team provided us with expert legal assistance on both matters. They were always very careful to explain to us what they were doing and why and what their actions would likely cost us in legal fees. Most importantly, we did extremely well on both cases and I have no doubt Harris Sliwoski was a big factor in that.
We have used Harris Sliwoski for legal help related to our international manufacturing. The lawyers with whom I worked had extensive familiarity with the international legal issues involved in our various projects and offered us key insights. I particularly appreciated how they always quickly and efficiently do what they say they will do and always within their cost estimates.
“Harris Sliwoski expertly guided us through the formation of our company. They continue to assist with necessary registrations and compliance with numerous regulations.

We expect to continue to use Harris Sliwoski on a regular basis as our company expands. They were also able to introduce us other professional experts. We would not hesitate to recommend Harris Sliwoski to any companies in need of legal advice.”
This law firm was a huge help as our company went through the process of commercial licensing in the California cannabis industry. They have helped us with a variety of legal issues in a timely fashion, while clearly communicating with us throughout the process. Everyone we’ve worked with at Harris Sliwoski is an expert in their field and we have always felt that we were in good hands through our legal representation.
Legal stuff is always scary. And I’ve had to play offense a couple times, begrudgingly. To have Harris Sliwoski have my back? It made things a lot less prickly. They quickly walked me through my options, and were refreshingly consistent in their 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, Harris Sliwoski quickly made things right.
I am impressed with this law firm.

I have been working with the lawyers at Harris Sliwoski for more than 20 years both as a business owner and as an executive at a large east-coast health system and that is because they have always efficiently provided high level and clear international law advice. Most recently, Harris Sliwoski provided legal support on many matters related to procuring medical products worldwide. Their support was particularly helpful to during the onset of COVID, when there was a big need for securing PPE quickly, all while navigating complicated international and domestic legal requirements. Harris Sliwoski’s team of international lawyers helped by conducting rapid-fire due diligence on potential suppliers, navigating the legal logistics for getting product from overseas and through U.S. customs, and drafting contracts to protect against various sorts of horribles. They did this by essentially providing what amounted to 24/7 service. I cannot recommend them highly enough.
