"There is truth in design. And design needs truth, to be relevant, to be seen, heard and understood. Settling for what has always been, is the easy falsehood we must turn away from.

In our first steps toward answers, solutions, pathways and possibilities … we begin, always with …what if…?”

Dr. Tammy wanted to create a company that innovates and problem solves real everyday problems. Her HErD Star is part of a utility patent the USPTO awarded her in May, 2025. The HErD trademark and logo both stand as tributes to her parents. Her father, Dr. Victor Hajjar began practicing in downtown Harrisburg, PA in 1959. And her mother, Maija, came to America from Finland. Dr. Tammy is fond of all things Finnish. The reindeer, a symbol of her love of her mother’s heritage, is also a symbol of female strength. Reindeer are the only deer species where the females have antlers. Del Sol Designs is committed to helping others and problem-solving through hard work, creativity and sisu. That’s a Finnish word, meaning an indomitable spirit.

"Several years ago I began experiencing the telltale signs of carpal tunnel syndrome and trigger thumb after practicing general dentistry for almost 3 decades. After my surgery and during COVID, I decided to try to figure out a way to re-design the handles of dental instruments so that others could avoid the same injuries I and countless others succumb to on a regular basis in this profession. After a lot of trial and error I discovered a way to avoid pinch grip pull forces that at the time, were the only means of retracting (as in strong tongues or heavy tartar). After many iterations I developed the HerD Star. I believe this small device can help others work more comfortably and efficiently without pain and injuries."

My father, who practiced general dentistry for 50 years, was also an inventor. I think I’m just a chip off the old block, as they say. My dad’s favorite expression for me was, “well at least she’s smarter than she looks”. God I hope so.

Good luck with our Stars and please let me know what you think. We will be developing a number of other ergonomic tools and instruments in the next couple years. Stay tuned, and take care.
