Zachary Yamin

Zachary Yamin



Zachary attended the University of Maryland where he took the same academic path as his father. Being raised by a mechanical engineer exposed him to this vast and inspiring field at an early age. On the other hand, it has also brought to light the devastating impacts that creations of mechanical engineers have on the environment. With a desire to join the effort to preserve our home without being called a “tree-hugger”, Zach entered the field of energy in an effort to sabotage the engineering world and change it from the inside. Being able to provide energy efficient business solutions gives him the platform to do his part in the movement toward a sustainable existence as well as to save you money.
