Parabis Group has posted a 5% rise in revenue for the 2012-13 financial year, while also making a dozen promotions at its Plexus Law and recently acquired Greenwoods subsidiaries.

Total income for the group has risen from £105.8m to £110.6m, a figure which does not include the recent acquisition of insurance dispute resolution firm Greenwoods.

The result comes after a year in which the firm converted to an alternative business structure and sold a majority stake of the business to private equity house Duke Street.

As a result of the deal, Parabis received a war chest of around £50m to fund ambitious growth plans. The firm, which also owns insurance litigation firm Cogent Law, said the Greenwoods purchase would take total turnover for Parabis Law to £150m.

The group grew the size of its partnership over the course of the year, with average numbers rising from 57 to 65. The growth included expansion into Scotland with new offices in Glasgow and Edinburgh, the latter following the hire of a five-strong team from Brodies.

Separately, the group has made 12 promotions, with two thirds coming from Plexus and the remainder from Greenwoods.

From Plexus, London-based quartet Justin Clayden (construction), Jamie Colman (clinical negligence), Allison Kemp (litigation) and Alain Orengo (professional indemnity) have been made up. They are joined by Leeds-based duo Stephen Lewis (property recovery) and Helen Randall (casualty), Manchester's Nicola Skeldon (acumen) and UK-wide Richard Guest (litigation).

The four promoted to partner from within legacy Greenwoods are Tim Ingram in Milton Keynes (criminal defence), Alex Puddy in Manchester (personal injury), John O'Shea in London and Andy Connor in Bristol (both property, insurance and construction).

Parabis CEO and senior partner of Plexus Law Tim Oliver (pictured) said: "Each of these individuals has proven themselves integral to the successful growth of the firm and we have been impressed with their commercial astuteness during a challenging time for the legal profession.

"Their hard work and longstanding commitment to the firm has led to increasing client demand for their specialist skills. We have ambitious plans for continued growth during 2013 and remain confident they will continue to contribute to the firm's ongoing success."
