P.C Hoag & Co., Inc - Certified NH Arborists

ISA Certified Arborists
Tree & Plant Health Care Services

Our company strives to provide our clients with services that are based on the most current scientific research available on the care of trees, shrubs and natural systems.

Pete Hoag started P. C. Hoag & Co. Inc. after graduating college in 1976. He then had the unique opportunity to study under the “world renowned” tree biologist, Dr. Alex Shigo. Dr. Shigo was, at the time, working on tree decay research entitled ‘Compartmentalization of Decay in Trees’ which, to this day, is an integral part of understanding the tree’s defense system.
