White Diamond was founded in 2019 by an experienced team of industry and community leaders: Mark J. Nesselroad, David Lorenze, Nick Colasante, and Mark R. Nesselroad (Glenmark Holding LLC). Having built a reputable, successful real estate model through commercial firm Black Diamond Realty, the group decided to expand into the residential market.
Securing a strong, well-respected leader was the critical first step. The founders called on licensed broker Melissa Hornbeck to fill that role. Melissa’s solid reputation, charming demeanor, and unwavering work ethic make her the ideal leader for a growing business.
To us, White Diamond is more than a real estate agency. It is an opportunity for our founders, our broker, and our agents to serve the needs of our community and build strong relationships with our West Virginia and Pennsylvania neighbors.
