The Making

of the

Nesting Dolls

To create a new multichannel campaign
for a leading pediatric vaccine manufacturer,
we used the same approach that's used
to create an animated film. Each doll
started as a black and white sketch.
The result: a Global Award—winning idea.

A Global


Even a few millimeters can create a big impact
when it comes to the effects of hypertension.
This message was brought to life in a Global
Award—winning prelaunch campaign for a
major pharmaceutical company.

A Spark

of Inspiration

Challenged with creating a new extension
campaign for the world's top-selling
pharmaceutical brand, we assembled talent
from across the TBWA\WorldHealth network.
SPARK™ is our very own approach to campaign
development — an intense creative firestorm
that results in better ideas faster and a more
rewarding experience for all involved.



Build one. Serve many. That was the approach
we took when developing the DROPS101™
Web Tool, an engaging multiproduct mobile
platform that helps Dr. Mom stay on top
of her family's health decisions. This Web Tool,
created for a leading manufacturer of eye
and ear care brands, was featured in
PM 360's patient-centric innovation issue.



Creative conventions in eye care feature
close-ups of eyes and smiling faces.
We helped a leading ocular anti-inflammatory
brand break through by taking a simple,
iconic approach. A muddy dog in a pristine,
white living room dramatizes every surgeon's
fear of postoperative "messes."

Don’t Get


This disease awareness campaign
was created for a leading manufacturer
of pediatric vaccines. Designed to
reach teens, parents, school nurses
and physicians' office staff, this initiative
helped raise awareness about the importance
of second-dose immunization against chicken pox.
