He’s driven on highways and crossed bridges, sat in sports stadiums and waited in comfort at airports that are the results of his legal handiwork. Wallace, a public finance partner at Bracewell in Houston, has led more than 300 muni-bond projects valued at $37.26 billion during the past eight years. And he is far from finished.
