Kerry established KLLA in 2002 after fifteen years of professional practice

with firms in New York, San Francisco and, most recently, in Boston with the award-winning Halvorson Design Partnership. At Halvorson, Kerry headed up the residential design division and lent her planting expertise to many commercial, institutional and park projects. 

She comes by her love of plants and natural areas from growing up on a farm in the Hudson Valley region of New York State. Her parents, recently retired, owned and operated a perennial nursery in the area for many years. Artistic talents run in the family; Kerry’s brother, Christopher Lewis, is a stone sculptor who is available for commissioned work. 

Kerry graduated from Cornell University with a BS with distinction in Landscape Architecture. She was also a competitive athlete with the Track & Field team. She holds certificates in Healthcare Garden Design (Regenstein School of the Chicago Botanic Garden) and Horticultural Therapy (Horticultural Therapy Institute and Colorado State University). When she is not designing or experimenting in her own garden, she enjoys romps in the woods with her Pembroke Corgi, Hudson, kayaking, sailing, watercolor painting and is an avid movie buff. 

Kerry has been a registered landscape architect since 1993 and is currently licensed in Massachusetts and Maine.
