House Mentor

My list of college degrees may be interesting but doesn’t carry the personal importance that my experience inside and outside the classroom of college students, young teens, and young children has brought. If I could condense my learning to one thought or bit of knowledge it would be this, “ALL humans need to know that they are valued and loved.” No matter where I go or where I have been, every experience of teaching and integrating my life with the lives of people, no matter the age, has always brought me back to this point that people need value and love from each other. Consequently, I have learned a lot from my students. What drives my inner engine is an honest interaction. I am an educator, an artist, a musician, a gardener, a mom, and a lover of creation in all of its forms and I will always be passionately curious.
