Employment Contract Review - Fast and Efficient

My cofounder and I were selling our company and wanted to be sure we had a solid employment contract with our acquiring company. We received a prompt reply when we contacted Mr. Deen, and he was thoughtful in his review of our paperwork. I highly recommend this firm for fast, efficient service and ex...cellent advice. Thank you Matt!

Fast, friendly, and professional legal support for my new business

Matt was extremely responsive and provided invaluable consultation while editing my first contract with a key client for my new business. The changes he made to the agreement paid for themselves, and it feels great knowing I have competent legal support going forward. Highly recommend.

Top Notch Business and M&A Attorney

My husband and I are small business owners in Oregon and were searching for an M&A Attorney to assist us with our business sale to a company in San Diego. We reached out to Matt based on his Avvo reviews and were so happy we did. Matt dispells every stereotype about an attorney. He was professional..., competent, responsive (even working the weekend and after hours to help us close our deal), pleasant to deal with and we felt like he always had our back. His rates are reasonable as well. Without him we would not have closed on time and we feel like our purchase agreement was well negotiated. We HIGHLY recommend him!!

Great small business attorney

As a small business owner, I've put off needing an attorney for as long as possible. I was referred to Matt by another business owner and I couldn't be happier with the work he did for me. He made filing an LLC incredibly easy and even helped me figure out the best structure for my business based o...n my current and future needs. He also drew up a contractor agreement that addressed additional issues I hadn't even considered and added a significant amount of protection for me and my business. I even referred Matt to friend of a friend and he was able to protect her business and keep her from entering into a bad contract with potential partners. He's always responded to my questions in a timely manner, has been transparent with the work he's done and is easy to work with. I believe he has my best interest at heart and will definitely continue to use him for all future business needs.

Partner agreement consultation

Matt was knowledgeable, patient and well prepared. Communication was easy and not pushy. Got answers to the most disturbing questions and overall was satisfied with the consultation. Thinking about hiring.

Avvo Rating

Our Rating is calculated using information the lawyer has included on their profile in addition to the information we collect from state bar associations and other organizations that license legal professionals. Attorneys who claim their profiles and provide Avvo with more information tend to have a higher rating than those who do not.

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
