About Kerns Bros.

Kerns Brothers Tree Service was started in 1973 in Delaware County, Pennsylvania by three of the five Kerns Brothers – John, Lohr (Teake) and Robert (Bob). John and Bob were working to provide a means of support to finish college and Teake to supplement his income as a Science teacher.  In the mid 1970s Teake left the business and went out on his own in Chester County and surrounding areas.  John and Bob continued working in the tri-state area.

In the early 1980s, John and Bob relocated the business to  Wilmington, Delaware. During this time, John was teaching full-time and working in the business full-time.  The mid 1980s saw the growth of the business, which necessitated increased employee hiring and educational training, as well as involvement in several professional organizations.

During this time, Kerns Brothers developed into a reputable tree care and landscape company serving thousands of satisfied clients in Delaware, Pennsylvania, Maryland, and New Jersey. Kerns Brothers currently has two divisions – Tree Care and Landscape Construction – with thirty professional, skilled, and experienced employees.

In April 2015, Kerns Brothers joined The Davey Tree Expert Company. This new relationship allows us to merge with a company that shares our core values and commitment to client satisfaction. While the logo and color of our trucks may change, you'll continue to receive the same expert knowledge and care from us, as well as the high level of client satisfaction and personal services you've come to expect.

Kerns Brothers Tree Service strives to provide the best possible tree and landscape care in the Delaware Valley. Our service is designed to exceed the expectations of our clients, and carries my personal guarantee.
