DPL Financial Partners LLP is wrapping up a big first year in business. The company, which works in the insurance business, has added 25 employees during the last 12 months or so, bringing its total to 27. And today, it celebrated the opening of a headquarters in East Louisville— at 1906 Stanley Gault Parkway — which quadruples its space from about 1,500 square feet before to about 6,000 square feet now.
