Q&A: Design firm MKDA’s sister-brother team Amanda and Brett Hertzler

MIAMI — At first glance, it might seem odd that a sister and brother run the Miami office of a New York design firm. But look deeper, and it makes sense for MKDA. The firm that Milo Kleinberg started in 1959 now is led by his two sons. The family-owned business clearly values sibling teams.

Interior designer Amanda Hertzler opened MKDA’s Miami office in 2013 and brought in her architect brother, Brett, two years ago. She leads the office and design side; he heads up architecture. 

The duo have been teaming up since they were kids making snow forts outside their farmhouse in Lancaster County, Pennsylvania. More recently, they collaborated in South Florida, when Brett had his own contracting company and Amanda had her own design business.
