Jeff has always been the first person I call when I need help with complex legal issues or am otherwise seeking practical advise. He's sharp, responsive and dependable.

Corporate Transactions and Contract Negotiations and Resolutions
Jeff has always done a fantastic job of keeping us up to date on the progress of our corporate transactions along with helping us make sound choices on issues we were not familiar with to protect us personally as well as our corporation. This is in addition to the numerous contract negotiations and resolutions he has helped us with throughout the years. I highly recommend his services.

Jeff's been our primary attorney and trusted advisor for nearly ten years, ranging from the day-to-day needs to critical litigation. There are obviously a slew of attorneys to choose from but I encourage you to put Jeff on your shortlist as you'll be pleasantly refreshed by his candidness and smarts.

Wide range of skills
We were starting an ecommerce website and needed some serious hand-holding to navigate design patents, trademark protection, licensing, celebrity endorsement and a host of other issues. Jeff was able to assist us in each and every area including setting up our new LLC. Outstanding work and detail oriented.

Flexible and Goal Oriented
Jeff and the Shustak team are very aware of our company's business capabilities, practices and goals. This foundation of truly understanding our business has helped us create a smoother flow of legal work and beneficial outcomes. We save time and money by working with experts who aid us in making good business decisions, not just good legal decisions. Jeff and his team are prompt, accomplish what they advise and provide great counsel overall. The firm is a great fit for our North America based, mid-sized manufacturing company and they understand the nuances and specific legal requirements of operating many businesses across multiple states.
