“I have practiced municipal law for more than three decades. During the last two years, David Tennant has advised me and, in turn, my municipal client, on the peculiar laws relating to our municipal interactions with an Indian tribe. He is a brilliant and persuasive analyst, adroitly balancing risk and reward. He also has a very winning track record. I could not recommend him more highly.”
