Greenberg Traurig Maher (GTM) has seen two of the three partners in its Birmingham office leave the firm, with energy & infrastructure partners Francis Patalong and Paul Kirkby both departing earlier this month.

The pair, whose new destinations are unclear, joined GTM in 2010 from DLA Piper to launch the Birmingham office alongside fellow energy & infrastructure partner Andrew Herring and DLA’s then UK energy chief Neil Upton.
