Manchester firm Pannone saw its turnover rise by 12 per cent at the half-year mark in a positive first six months.
Income rose to £20.5m for the first half of the current financial year, compared with £18.5m in 2005.
The increase is lower than the firm's 16 per cent turnover growth for the full year between 2005 and 2006.
However, managing partner Joy Kingsley said signs were positive for the second half of the year and that the firm is on course to break through the £40m barrier.
"We'll definitely beat last year's turnover by 15 per cent, maybe more," she said.
Kingsley added that the continued growth was due to investment in people during the last year, including the absorption of four partners and a number of other fee-earners from local firm Wacks Caller in June this year.
