Meet the Sims

Since 1972, Garry and Susan Sims have provided premium health care services for trees. Along with their son, Kevin, and daughter-in-law, Nicole, the Sims have dedicated their lives to the preservation of trees. (Picture: Nicole, Kevin, Susan, and Gary)

Education

The Sims family have not only become known for their quality tree health services, but also as educators. In 1996, the Sims family started the Sims Tree Learning Center (TLC), a 6 acre botanical garden and research facility sponsored by Sims Tree Health Specialists Inc. The facility houses multiple types of gardens including a cactus and succulent garden, an English garden, and one of the largest collections of Palms in the Inland Empire.  Educational tours are free of charge and are open to the public by appointment. Adult and youth education seminars and workshops are hosted in the antique museum.  With the museum being filled with antique cars, biological samples, and antique tools, it is nearly impossible to walk out of Sims TLC without learning something new. 

Improved health and safety of trees

As with the human health industry, constant new developments and discoveries are made about the health and well being of trees. The arborists and technicians of Sims Tree Health Specialists are constantly attending seminars and workshops to keep up on the latest treatments available. You can feel confident knowing that you are receiving the latest information on any new treatments, pest, or disease affecting your area or species of tree.
