“Dan Kerlin is an excellent professional planner and a talented Landscape Architect. I was fortunate to have worked with Dan on a joint venture needs assessment and large scale Master Planning project in Loudoun County Virginia. Dan performed at the highest level and met all commitments and deadlines while performing under extreme pressure and a very limited timeframe. It was a pleasure working with Mr. Kerlin and I look forward to the opportunity to work together in the very near future. I highly recommend Dan for any related professional position.”
