Scott C. Plein is Principal of Equinox Investments, LLC, a real estate investment, development and management firm specializing in community planning, entitlements and project development. A lifelong resident of the Commonwealth of Virginia, Plein began his career in the late 1970’s when he founded KT Enterprises, Inc., a local landscape development firm. Today KT along with its affiliate companies provides turn-key site development solutions for some of the most prestigious home builders, developers, and commercial contractors in the Washington, D.C. metropolitan area.


Plein has served on several local and regional boards including the Northern Virginia Transportation Alliance and the Northern Virginia Chapter of NAIOP, to name just a few, and is a past president of the Northern Virginia Building Industry Association. He is currently president of the Dulles South Alliance, an association of business and resident leaders dedicated to providing an open forum to the public on the future development opportunities in the Dulles South region.  He also chairs the Building and Development Committee for the soon to be constructed Capital Caring’s ‘Adler Center for Caring’, a state-of-the-art inpatient hospice center.


An involved citizen in the community in which he lives, Plein recognizes the great responsibility of giving back and supports many non-profits and charitable groups through not only a devotion of financial resources, but more importantly, time. From his mentorship of young leaders in commercial real estate through the George Mason Center for Real Estate and Entrepreneurship program and NAIOP Northern Virginia’s Developing Leaders, to his operational guidance and mentoring advocacy with Asian American and other minority students (AASuccess), Plein is dedicated to helping advance the social, personal and professional fulfillment of our young citizens.


In his spare time, Plein devotes himself to the White House Farm Foundation, a nonprofit educational foundation established after his purchase of the 270 acre historic ‘White House’ property in Luray, Virginia.  Through the Foundation, Plein hopes to enrich individuals with the knowledge of and involvement with our natural ecological systems, sustainable agriculture, holistic community planning, conservation, and respect for local history and culture.

The White House Farm Foundation is a non-profit organization dedicated to learning how to live more sustainably on the land and use our natural resources wisely.  Their desire is to work with the community and their partners to answer some of the large questions facing conservation and development today:

1. How do we live in balance with our environment?
2. How can we enhance the landscape to feed wildlife and ourselves?
3. Why is it important to conserve land?
4. How can we support our local economies?
