Crass Tree Experts was founded in 2022, but the knowledge behind it goes back three generations. Owner Nathaniel Crass grew up learning the trade firsthand, carrying forward decades of hands-on experience and skills passed down through his family. That legacy is the foundation of everything we do, from the smallest trim to the most complex removal.
We are a family owned and operated business proudly serving York, PA and the surrounding communities, including Stewartstown, Red Lion, Shrewsbury, and New Freedom. Our team specializes in tree removal, tree trimming and pruning, plant health care, and storm damage cleanup, and we’re available around the clock for emergency jobs when storms strike. We’re also licensed (PA License #PA224977) and committed to holding every job to a high standard of safety and professionalism.
At Crass Tree Experts, we believe good tree care starts with treating people right. We offer free estimates, fair and transparent pricing, and a military discount to show our appreciation for those who’ve served. Whether you need routine maintenance or storm recovery, our goal is the same every time, quality work, honest service, and a property left better than we found it.
