to bring something back.”
Stewart’s payback is in networking with others
who want to be best in class, but who face the same
equipment issues.
Clear Direction
TMC of Tomorrow is important because it is giving
program participants “a clear path and direction
for how to get more involved within TMC,” says
Amanda Schuier, director of marketing, Waller
Truck Company, and another member of the
inaugural ToT class. “Eventually, we will all be
‘adopted’ by study groups where we’ll learn what
it’s like to help with RPs creation, chairing task
forces and other projects.
“When I started with TMC back in 2008, I had
no idea how to get involved. Getting the leadership
program group together allows us to share our
experiences about TMC, as well as our careers,”
she adds.
ToT program participants are required to
complete online tests about basic TMC information,
such as the study group and task force
organization, as well as navigating TMC Connect,
the TMC’s online social networking and collaborative
platform.
Professional Development
“My heart will always be with the technician,”
says Daniel Mustafa, assistant manager, technical
development, TravelCenters and also one of
10 members of the inaugural ToT class. He was
delighted to hear a panel of expert speakers say
they all started their careers as technicians.
“I share the mindset of those running TMC,
show so I feel I belong in the organization,” he
adds, explaining that he fi rst participated in the
TMCSuperTech competition and judged one of the
competition’s Skill stations prior to attending the
TMC’s fall meeting.
Th rough the ToT program, participants will
develop new business relationships and friendships
through peer networking opportunities;
increase their knowledge of trucking, regulatory
and leadership issues through professional development
opportunities; and establish themselves
as future TMC leaders.
“In our fi rst meeting, the TMC of Tomorrow
group had a leadership program that was phenomenal,”
Waller Truck’s Schuier says. “Th ere were a
lot of great nuggets that applied to my job on a
daily basis. I am looking forward to spending the
next two years learning with this great group.”
JANET HOWELLS-TIERNEY serves as
the director of council development for
TMC the only industry association that
is focused solely on truck technology
and maintenance. She is responsible
for the recruiting and building of TMC’s
membership, and also functions as the
primary member services link for TMC’s
membership of more than 2,400 industry
practitioners.
