Meet our Landscape Designers!

Jamie Newell

OurDesignTeam1Jamie is a graduate of the University of Maryland Landscape Design Program, and he received additional training at Brookside Gardens in Wheaton, MD.  A designer at Johnson’s since 1993, Jamie has the training and experience to undertake a wide range of landscape projects, including patios, entries, decks, hot tubs, and water features.  

Jamie likes to offer his clients a comprehensive plan that can be installed in phases or all at once. His designs are carefully prepared, and he enjoys blending elements of English, Japanese, and “naturalistic” garden styles in his plans. And with his extensive horticultural background, Jamie can also help his clients select the right plants for seasonal color, deer resistance, low maintenance, and most importantly, lasting results.

Mary Gill

OurDesignTeam2Mary graduated from the George Washington University Landscape Design Program, and she has since designed numerous landscapes and gardens for satisfied clients across the Washington metro area.

Mary’s primary goal is to create landscapes are unique and sensitive to her client’s needs and wishes.  Equally adept at designing large formal yards or small intimate gardens, she likes to bring color and texture into her plans to maximize all-season interest and beauty. Mary particularly likes the challenges presented by clients with limited space or prevailing shade, and she is skilled at creating new outdoor living spaces that are enjoyed the year round.

Lillian Barrere

Lillian earned her degree in Horticulture from the University of Maryland, and she has over ten years’ experience in residential landscape design.  Her extensive background allows her to offer her clients a wide-range of design styles, from the small and intimate, to the grand and formal.  She also likes to use native plants to support the environment and local wildlife.

Lillian enjoys the challenge and artistry that each new project demands.  She particularly likes to explore the dynamic pairing of beautiful and fun plants with the cool, enduring materials of wood and stone.  Her ultimate goal is to create outdoor spaces that are functional, beautiful, and unique for each of her clients.
