There are so many wonderful people with expertise in many different disciplines who work at Children's Care, and they come together every day to do what is in best interest of the individuals we serve. The best part of my job is seeing my students make progress, knowing that I am an important piece of their lives in teaching them skills to be successful. My students are my focus and the heart of my career.
