    I love giving back to my community by using my knowledge as a student at California State University, Monterey Bay. I love to help pets from all around and make sure they are in their best healthy condition. I love working here because they help me learn and practice new skills and guide me towards my career path.

    I spend my free time by exercising, going to the beach, hanging out with friends or playing with my family dog, Fergie. I also enjoy watching movies and playing board games with my family.
