Twenty years ago we chose John and Debbie to help us develop a name, corporate identity and marketing program for our new company, Optimum Solutions Corp.  We did well during the ensuing years, yet in that same time period, the world, our industry and company greatly changed. Facing new challenges and opportunities, we decided the time had come for us to rebrand OSC and once again turned to John and Debbie for help.  We're glad we did; they're the professionals you will want on your team too.

Branding Without Boundaries


Deborah Darnulc

Deborah Darnulc started her career over 20 years ago working at the Manhattan advertising agencies of N.W.

While Deborah specialized in the healthcare industry, her knowledge of consumer marketing was put to use in helping HLD’s consumer electronic, financial and banking clients grow their business as well.

And now partnering once again, Deborah and John have started The Brand Compound.
