Hello! My name is Kassandra, however, I prefer to go by Kassie. (I apologize that video in my profile is old, I will update it when I can). I am a student who works as a waitress as it is accommodating. I am currently enrolled at SJSU as a Psychology major with a double minor in Child Development and Sociology. I’m looking down a career pathway of becoming a Child Psychologist, therapist/counselor, school counselor, behaviorist therapist or something along that path. I love working with children and I want to make a career out of it. I have received AAs in Psychology, Allied Health, Natural Science and Health Education. I love to help others. I’ve always wanted to follow in my grandma’s footsteps with saving lives and making a difference by working in the medical field. I am COVID-19 vaccinated and boosted as well as flu vaccinated. I have also received all my other vaccines. My experience with children goes back to when I first started babysitting at the age of 12. I have worked at day cares where I have experience with children from infancy to 15 years of age. I am comfortable with all age groups. I do not smoke. I love animals as well so pets are never an issue! I have experience house sitting/petsitting as well. I have been house sitting/petsitting since I was 13 years old. It first started out with watching my neighbor’s house and cats while they were gone and progressed to dog sitting/cat sitting at other people’s houses. I am very responsible and respectful of other people's homes. I clean up after myself and make sure the house looks like it did when I arrived.
