oha program manager Josh Kerber

Josh Kerber, HI USA NW Educational Programs Manager

Growing up in a household of educators off and on a family dairy farm in rural Ohio, Josh's fervor for experiential education started at a young age. As his passion for travel education mushroomed, he found himself cruise directing in China, harvesting rainwater on an eco-village in the US Virgin Islands, clearing trails in the Grand Canyon National Park and committing to a year of national community service through Americorps NCCC.

Josh has also spent years in Southern California leading day and overnight programs for youth, with a focus on science, outdoor education and leadership development. He believes nature is good for the soul and that travel brings forth compassion, moxie, and fortitude.


OHA naturalist Neysa Budzinski

Neysa Budzinski, OHA Naturalist

Neysa began learning about the natural world from an early age from her father, a botanist, and her mother, an avid gardener and animal lover. She loves nothing more than to comb the wild for her favorite medicinal plants and then show them to anyone who will listen and look. She thrives on traveling to places that have proud ancient cultures and excellent food. Her favorite thing about traveling, besides eating and gawking at architecture and art, is meeting people along the way -- usually in hostels. She loves to create, dabbling in photography, origami, and knitting, as well as the fine arts.

Neysa currently resides in the Bay Area because she enjoys the culture and diversity that it offers.
