spent 30 years at the Colorado Dept. of Public Health & Environment, solving numerous environmental /ecological issues. Now he spends his time in his greenhouse, grape vineyard and vegetable garden, which he’s developed for over 25 years. Jeff not only has a horticultural degree but has a greenhouse legacy with both his grandfather and mother having managed greenhouses. We’re delighted we have him to share his knowledge and opinions with Harlequin’s customers.
