Dave Schlom

Host, Blue Dot

Dave Schlom has taught the physical sciences at Corning Union High School since 1991. A lifelong amateur astronomer and astronomy educator, he has a passion for both the earth and the space sciences, which are the principal areas of focus for guests on Blue Dot. He started doing radio interviews on space and astronomy topics for local stations like KFM and KPAY in the 1980s and into the 90s, where he was a popular go-to guest for local radio personalities. He is also an expert on the history and geology of Lassen Volcanic National Park, where he has served as a volunteer for decades. Dave enjoys a quiet life at home with his partner in life, Cheryl, and their two dogs, Elvis and Pearl, at their Red Bluff residence.
