Doane Grant Thornton adds CPA teams in Ontario and British Columbia

Doane Grant Thornton, a national mid-market accounting and consulting firm, this month welcomed accounting teams in Markham, ON and Nanaimo, BC.

Joining Doane Grant Thornton’s Markham office from RSP are Darryl Rosenberg, Steve Rose, Kenneth Lee, and their team.

“We pride ourselves on delivering tailored, forward-thinking solutions that give our clients a headstart in today’s evolving business landscape. Joining Doane Grant Thornton LLP enables us to continue that commitment with enhanced resources and a broader network of support,” said Rosenberg, who joins Doane Grant Thornton as a business advisor.

Rosenberg brings more than 35 years of accounting and tax advisory experience. He most recently spent six years as a partner at RSP and before that spent 28 years with Shore Neman & Rose, where he was also a partner. He began his career as an accountant at KPMG.

Joining Doane Grant Thornton’s Nanaimo office are Trevor Topping, Aaron Dovell, and their team from the Smythe office in Nanaimo.

“Joining Doane Grant Thornton marks an exciting step forward for our team and clients. It allows us to provide even better service to our clients on Vancouver Island by giving us access to greater resources and a broader network,” said Topping, who joins as a principal.

Topping has 20 years of experience in accounting, valuations, and M&A advisory. He previously spent 10 years with Smythe, where he was a partner, and eight years at Berris Mangan, where he was a senior associate in the valuations practice.

DGT last month acquired boutique CPA firms in North Bay, ON and Red Deer, AB.
