“Mark is a wonderful, multi-tooled litigator, who adds real depth of experience to our trial practice, on both complex civil litigation and criminal defense matters. Mark's prior work as a public defender and a public interest litigator makes him unafraid to take on tough cases in pursuit of achieving great results for our clients,” said Jenna Dabbs.
