Alyssa $27 per hour for 1 child

Hi families! I am a middle school teacher (cooking-- yes, it exists!) with nearly twelve years in the classroom. Originally from the midwest, I spent many summers growing up working as a nanny, babysitting for neighbors, and eventually working in summer camps and a daycare for four years during college. I have always been in roles working with children of various ages, and my career in education has allowed me to continue fulfilling my passion. I teach my students how to cook, shop, and plan meals for themselves, in hopes of giving them confidence in the kitchen. I love what I do, even on the most chaotic days! You can expect me to drive myself to your home, arrive on time, interact and engage with your children, follow the directions you provide, and leave a clean house. My teacher "toolbox" allows me to adapt and create fun activities for us to do, related to the age and abilities of your child(ren). I love creating memories with your kids while you enjoy your time away, giving you peace of mind and the freedom to focus on yourself. I am happy to do what I can around the house to help support your family, as well as take care of any pets you may have. I have 3 dogs myself, and am comfortable with a variety of tasks necessary to keep your animals happy.
