Michael Undlin /

‘Assistant to the CrabbieMaster’


Anyone who knows Becky knows teaching kids is more than a job – it’s her passion. Mike still remembers her excitement when she first told him, now about 30 years ago, how great her days had been since she and the kids had learned to “Beat the Crabbies!” Shortly after that, Mike made it his mission to help her develop the concept for use in preschool. Over time, he realized Becky needed to take CrabbieMasters beyond her classroom. With his encouragement, Becky led the way as they drafted scripts. Mike found great professional help for illustration and editing, while managing the details related to putting together the book series. Of all the positions he’s held, from summers driving farm equipment to corporate sales and marketing roles, his favorite title is “Assistant to the CrabbieMaster.”



Andrea Undlin /

M.A., Licensed Marriage and Family Therapist

Andrea was a preschool student during the early years when Becky was launching the CrabbieMasters idea in her own school. She holds a bachelor's degree in Family Social Science from the University of Minnesota, and a master's degree in Marriage and Family Therapy from Saint Mary's University. She currently works in private practice, and as a therapist and supervisor at a local non-profit that specializes in child and family development. Andrea is passionate about working with children and families. She has a firm belief that the wellbeing of children starts with good parent-child relationships.



Jenna Bemis /


Jenna holds a doctoral degree in Psychology from the University of Minnesota. She also studied in the Department of Family Social Science and the Institute for Child Development. In 2013, Jenna began training through the Center for Mindfulness, founded by Jon Kabat-Zinn at the University of Massachusetts, and in 2016 she began studying the Philosophy of Yoga. In 2017, she trained in Peace Literacy, a program developed by Paul K. Chappell, sponsored by the Nuclear Age Peace Foundation. After a decade of specializing in trauma recovery, she took a big leap at the end of 2017, closing the doors to the practice of psychology to orient towards yoga and peace activism. She is currently developing a program called Compassionate Presence with Animals to help people have a greater sense of connection in their relationships with their 4-legged companions under the mentorship of Stormy May, documentary writer of The Path of the Horse. Jenna also devotes a portion of her professional time to program development to help bring CrabbieMasters to parents, educators and other professionals.
