“We’re into getting deals done.”

Mark brings experience advising some of the largest companies in the world on industry-altering transactions in Gibson Dunn’s corporate department to entrepreneurs, searchers, and dealmakers in small- and mid-market transactions.

Mark lives in Santa Teresa, Costa Rica and San Diego, California with his wife, Kassidi, his son, Sage, and his dog, Tipsy. He can’t do anything until he’s surfed. It’s a curse.
