When Luke Barrett went from private practice to in-house nearly 20 years ago, he made a pact with himself.

“The bargain that I made was that if I was going to move from private practice to in‑house, I wasn’t going to rule a line under the level of knowledge that I had on the day I left private practice. I wasn’t going to timidly outsource any query that I hadn’t dealt with before or didn’t know the answer to,” he said.
