Hunterdon Hills Animal Hospital wins 2015 Merit Award for Hospital Design! Hunterdon Hills Animal Hospital is one of 10 veterinary facilities Sweetwater has completed or commenced, and of those, the latest of 3 recipients of the Veterinary Economics Hospital Design Award. Constructed in a “milk barn” style, with a carefully erected, reclaimed 19th-century Pennsylvanian barn serving as the reception area, the hospital mixes nostalgia and state-of-the-art in rural New Jersey.
