Hi! My name is John Holtz; I’m a custodian at St. Mark Parish. I’ve been married to my wife, Jan, for 41 years. I grew up in the Strawberry Point area and farmed on the family farm for several years. For many years, I was a truck driver, retiring from that profession in the fall of 2015, when I started at St. Mark. I love gardening, so each summer I plant a large garden, sharing my produce with friends and neighbors. I always like to try something new, so this year I planted black tomatoes. It’s still too early to tell if they are a success or not.
