“I love balancing my work as a psychologist by spending time with my family. I enjoy traveling, hiking and biking, reading, cooking, and trying new restaurants with friends. Though I am no fan of Minnesota winters, I enjoy spending as much time as possible outside and find the spring, summer and fall delightful.”
