Hengler received a formal undergraduate education in Italian Literature from three universities (University of Kansas, Lorenzo De’Medici, and the University of Oregon). He received his graduate degree in fine arts with a focus in Glass from the University of Hawaii, where he is currently a Graduate Teaching Fellow.

His efforts to tie himself to the 2000-year-old tradition of glass in Europe were further rewarded and developed through his travels in the United States. From Boston to Oregon he continued to hone and gather tricks and skills at various studios. Although he settled in the town of Eugene, Oregon for five years, he continued to travel and work throughout the US, while acting as Director for the Eugene Glass School, teaching high school students torch-working, and receiving a one-year Artist in Residence. His residence resulted in a 2009 solo exhibition at the George Kjaer Gallery.

During his time at the University of Hawaii, he has received numerous grants, awards, residencies, and exhibitions. He has performed at The Contemporary Museum in Honolulu, HI, taught numerous workshops, and has artwork in collections around the world.
