Why Choose Michael?


I have worked with many lawyers on different business ventures over the years, but I would recommend Michael above them all. He provided my start-up with all the legal information that we needed. He took the time to learn about our market and what we sought to create, and he was able to provide the tailored counsel that helped us move forward.
