Griesing Law is highly responsive, knowledgeable, and willing to work to achieve a win-win on fees. They are one of our "go to" firms.

They are responsive to requests and provide an excellent client service experience. I highly recommend Griesing Law.
Commercial Litigation
The fees were a bit higher than we typically pay for this work, but my team member reports that the attorney we worked with from Griesing Law was great.
Closely Held Companies and Family Businesses Law
