Gammon & Grange, PC has represented our non-profit firm for over four decades! They are true professionals and experts in many fields that have been critical to managing our faith-based non-profit. We can unreservedly recommend them.

For more than 40 years of recommending nonprofits to Gammon & Grange, especially churches and faith-based organizations, not one has reported any concerns. They have a mid-size firm with some specialization that is very client-oriented. Couldn't speak more highly of their attorneys.

They negotiated a larger settlement than I expected by at least triple the amount… Thanks again to Bob for all the good advice during that time… I did recommend you guys already because I think you’re from the old school… You care about how you're getting it done and the people you’re serving.

I have known Chip Grange for almost ten years. I find him to have a great balance of humility and assertiveness in speaking to issues and to be extremely knowledgeable in many topics. He is a great listener, leader and friend to me, our church, and many non-profit organizations that need his expertise.

I’m so grateful for the expertise and counsel of G&G's Derek Gaubitz. He has provided timely, professional, and constructive solutions for incorporating our religious school as a tax-exempt non-profit, reviewing and drafting employment contracts, and helping us form as a faith-based ministry. His trustworthy guidance has been critical to our launch.

As an executive of various organizations, I have worked with the skilled and effective attorneys at Gammon & Granges over the past 20 years. Everything from corporate legal matters to Intellectual Properties, to litigation. I have been well served by G&G and recommend them regularly when asked who to use as an attorney.
