Commenting on her appointment, Powell said: “I wanted to join an independent firm that was firmly focussed on providing high quality advice to mid-market companies and BHP was the obvious fit.
“I’m really excited to get stuck into my new role and get out and about meeting lots of new businesses.”
Joint managing partner Hamish Morrison added: “Joanne brings with her a wealth of experience and will be a great addition to our growing team. Joanne boosts our tax team to 57, making it one of the largest in the region.
