LEXEe navarre

Being at HVE since 2019, Lexee has enjoyed every aspect of the structural design process, from getting to work on little additions and remodels to full blown brand new mansions. In the residential field, finding out the secrets of a family dwelling floor framing or attempting a new concept an architect proposes always offers a new challenge day to day. When Lexee is not working she spends her day volunteering at a horse rescue, working with horses to help find them future forever homes by preparing them to be good natured citizens. Otherwise she will be riding her own horses, camping with her friends and exploring new places.
