Intreegue Design is owned and operated by its President Colleen Vacelet. The firm was founded in early 2013. Although young, the Intreegue leadership and staff have copious years of experience and knowledge in the field.



Colleen E. Vacelet, ASLA, LEED AP BD+C graduated with a double major in Landscape Architecture and Horticulture from the University of Maryland. She is known throughout the field for her passion of the discipline of Landscape Architecture. This passion has taken her near and far, and back again. She has lived and researched in other countries to garner new cultural connectivity and hone her design skills. She has over 14+ years of experience working for a variety of well established firms along with her tenure at Intreegue Design. Throughout her career she worked on a variant of projects. Her experience spans from estate planning, high-end residential, institutional design, forest conservation, botanical garden design, children’s garden design, master planning, workshop facilitation, horticultural expert, to even installation.

She is a certified forest conservation planner and a LEEP AP BD+C. She served for 8 years on the board for the MD Chapter of the American Society of Landscape Architects concluding with service as President of the Executive Board. To bring her passion into form, she began teaching at the Catholic University of America for the Graduate Architecture Department in 2010. Since then she has come home to the University of Maryland, her Alma mater, to join the faculty as an Adjunct Assistant Professor for the Landscape Architecture Department.

When not at work, she can be found in her Maryland garden with her bees, or with family at their gardens in Nancy, France.

Intrigued? That’s how we approach our designs, to make them “intreeguing”, to connect with the passersby, coax visitors in, bring excitement to what perhaps, was mundane. We bring this sense of “intreegue” to each and every project.

Unlike most design firms in this industry that are named after the founder, Colleen Vacelet wanted to set Intreegue apart. The name is based not on our founder but on our passion that we, along with our client’s vision, is brought to life through concepts presented. Ego’s do not surround our designs but instead client collaboration and inspiration are the main focus.
