Alessa is the most understanding, patient, loving, and compassionate person you will ever meet. Much like her name's origin she is a "noble defender" and puts others needs before her own and does her best to serve mankind to make this world a better place. She is able to connect to others in a very deep and intimate manner due to her trustworthiness and unconditional love for others.
"Alessa has always been there for us, no matter what we do, she loves us no matter what...do you know anyone else like that?"

"No Alessa is one of a kind, and the most beloved friend I have. I love her a whole lot, and she loves us a whole lot too"
