Joseph S. Groh
Foundation Recipient Charlie Yerger.
Charlie’s initial degree was not predictive of what turned out to be
his passion. He turned a degree in EMS/Paramedicine into a career of
working with HVAC control systems. His HVAC career started as an
installation foreman for a controls contractor, which led to working
as a technician for a large residential and commercial HVAC
contractor in central Texas. In 2006 Charlie joined Johnson Controls
Inc. as a Systems Technician on a major projects team, doing service
work in specialized building systems areas.
In 2013 Charlie was diagnosed with muscular dystrophy!
Several years later the diagnosis was narrowed to that of Bethlehem
Myopathy, an inherited movement disorder characterized by
progressive muscle weakness and joint contractures in the fingers,
wrists, elbows and ankles. Doctors came to this diagnosis after
several abdominal surgeries following a muscle biopsy. After the
original diagnosis, Charlie was only able to work about 8 months
over the next 3 years due to hospital stays and doctor appointments.

persistent however, and transitioned to working as a remote
product support technician for Johnson Controls two years ago.
This enabled him to work from home, providing technical support
for the FX and Metasys product lines. The change however meant
he was no longer able to work in the field, thereby losing a
considerable amount of pay. Charlie’s condition now requires
that he use a power wheelchair, and he was seeking a lift for
his truck which would enable him to transport his power
wheelchair wherever he goes. One day Eric Groh called into
Johnson Controls for technical support. Eric is employed in the
HVAC controls industry and is also on the board of the Joseph
Groh foundation. In talking with Charlie, Eric learned of his
situation. That led Charlie to petition the foundation for a
wheelchair lift for his truck.
Thanks to your support, the foundation was able to grant
After receiving the lift, Charlie said “I am so so thankful for
everything that you and Eric have done for me. Without the Groh
Foundation, I would still be struggling with a manual chair and
not having enough energy to do anything more than sit. Thanks to
you, Eric and the entire Groh Foundation. Let me know how I can
help your foundation.”
