NDH Advisors LLC, a Chicago-based accounting business and a portfolio company of Unity Partners, has acquired tax and accounting firm Stratus Group LLC.

Established in 2002 and located in Leawood, Kan., Stratus offers tax and outsourced accounting services to high net-worth individuals and small businesses. In addition to the firm’s tax focus, Stratus provides services such as estate planning, succession planning, cash flow reporting and bill pay, recordkeeping and money manager selection and evaluation.

“Since our investment in NDH, we have prioritized implementing our ‘Partner & Propel’ strategy to find great firms that fit well with NDH and embrace our goal of building better together as we expand our footprint,” says Peter Cozzi, team lead at Unity Partners. “Stratus is a phenomenal business to partner with and we’re eager to continue to drive additional growth with NDH in this highly fragmented market.”
