Veteran CPA consultant Gary Boomer has been chosen as MVP by online accounting software vendor Xero. And if we need proof that the head of Boomer Consulting is all-in with the New Zealand-based Internet software company, it came this week as Xero handed out awards at Xerocon, the first edition of that show in the United States. Boomer is also a member of Xero's Advisory Council, as is Doug Sleeter of the Sleeter Group.
