Lindsay Ennis

is an Engineer Technician with Peak since 2013, with drafting and design experience in the fields of structural and civil engineering. She is experienced in the design of residential structures and is familiar with applicable Residential Codes of New York State and local code requirements. She is also an Accredited LEED Green Associate.

Lindsay spent most of her early life aspiring to be a fashion designer; attended FIT, interned in Manhattan, and attended seasonal fashion previews with industry leaders. Shortly after moving to Ulster County, she enrolled in the Drafting and Design program at SUNY Ulster and embarked on a new career path. She has taken the essence of what she loves most about fashion; the construction of a garment, the clean, straight lines of a perfectly sewn seam, the way a well-assembled wardrobe could tell your life story – and has applied that to residential design.

Today, Lindsay works directly with clients providing them fresh ideas and inspiring images, applying the same fundamentals and esthetics of fashion while taking into consideration every detail of the home to make sure it tells your (the clients) life story.
