Pittsburgh Landscape Design Company

RJK Landscape Designs is a Pittsburgh based landscape design company, owned and operated by Landscape Designer, Ron Kotcho. We specialize in residential design, installation, and aftercare.



Ron Kotcho was born in Pittsburgh, Pa. in 1953. He is an accomplished landscape designer specializing in residential design, installation and aftercare.

In 2012, one of Ron's designs was chosen for inclusion in the Smithsonian's national archives of American gardens. His work has also been featured in the Pittsburgh Post Gazette, Shady Avenue magazine and the Pittsburgh Quarterly.

After living and studying in the Netherlands and Italy for four years, Ron received a Chancellors scholarship to the University of Pittsburgh where he graduated summa cum laude with a degree in Art History. After graduating, he worked for Medrad Inc. as International Marketing Manager. After traveling extensively in his position, Ron changed course and moved to Boulder, Co. to contemplate the meaning of existence. He concluded that, at the age of four, the day his mother gave him a Marsh Wheeling cigar box filled with marigold, zinnia and Morning glory seeds his destiny had been sealed. Thanks to the wisdom of his mother, the seeds of a lifelong passion for gardening and design had been sown. Today, marigolds and zinnia are a tough find in Ron's designs. The objective now is to create garden spaces that are balanced, cohesive, purposeful, inviting and compliment the architecture and the design site. Ron approaches each design as a living, growing work of art.

In his spare time, Ron enjoys doing art work. He works with various materials to create multimedia collages. He loves regional Italian food and is a cooking enthusiast.
