"Hello parents! I'm excited to introduce myself as a caring and dedicated individual with a passion for working with children. As a substitute teacher, I've had the opportunity to work with students of various ages and backgrounds, honing my ability to adapt and connect with each unique child. Although I only hold a high school diploma, I'm currently pursuing higher education and actively seeking ways to grow and develop my skills. What sets me apart is my extensive experience caring for my niece and nephews since they were born - I was just 14 when they arrived! This experience has taught me patience, creativity, and the importance of providing a nurturing environment. When I'm not substitute teaching or studying, you can find me expressing my creativity through painting or exploring local libraries and parks. I'm excited to bring my energy, enthusiasm, and artistic flair to your family and provide top-notch care for your little ones!"
