Our Team

Martin J Silverman

President/Sales Manager

Martin started the company in 2001 after graduating from Purdue University with his Bachelors in Landscape Design and Horticulture. Like most small businesses he began the company by not only selling the work, but also performing it. He started the business as a small 2-man operation and it has since grown steadily over the years to now employ over 45 people.

Martin has been married to Katie for more than 15 years now and has 2 great kids, Audrey and Jonathan. He has always enjoyed working outside and building projects since he was younger. Martin’s biggest reward is to see a project that the team at Martin John envisioned and developed go from a blank canvas to the final product to a satisfied client for years to come.
