Hella Keppo’s early interests in plant life led the way to a degree in Horticulture and Business from the University of Guelph in 1995, and shortly after a Master of Business Administration in Agriculture in 2001. Through this gained knowledge, Hella directly trains her employees to correctly implement horticultural practices in their daily work approach. Her down-to-earth philosophy is that plants do not end their own lives, they’re left to die. Therefore, all that is needed by plant custodians is to place the proper plant in the right environment and then provide it with everything it needs to survive – and it will.

Hella is a Certified Horticultural Technician through Landscape Ontario and the Associated Landscape Contractors of America (ALCA). She is also very active in the Interiorscape industry, as a founding member and Treasurer for Landscape Ontario’s Interiorscape Commodity Group.

Projects and Associations

Always looking for an opportunity to enhance indoor environments, Hella became a founding partner of the University of Guelph-Humber’s Plant Wall Biofilter project which is not only an aesthetically impressive focal point but also actively cleans the air. She and her team also sponsor the Green Plants for Green Buildings initiative that spreads the word about the benefits of indoor plants.

Hella has published several articles in a variety of magazines including “Your Workplace” and “Canadian Property Management”.
