What Clients Say
"I had a co-founder situation and needed an operating agreement that protected both parties. Rosenberg Fortuna set everything up properly, including a detailed profit-sharing and buyout clause. Saved us from a very messy future dispute."
"A vendor breached our contract and it nearly shut us down. John Fortuna was aggressive and strategic — we settled at a number far better than I expected in under four months. Excellent representation."
"We sold our family business after 20 years. David Rosenberg guided us through the entire transaction — due diligence, representations and warranties, closing conditions. Very thorough, very professional."
