Angelica

Angelica Burrier

Realtor

Angelica was basically born swimming in the Guadelupe River that ran behind her childhood home in New Braunfels, TX. You can often find her in or near a river now. Unfortunately, she spent her teenage years in the foster care system moving around Texas a lot but spending most of her youth and adult life in San Antonio where she graduated High School and began her career and family.

Because of her experience in the foster care system she is very passionate not only about nurturing her own two wonderful children but all her fellow foster brothers and sisters as well. She is now in the process of starting up a non-profit organization, called ThriveSmart, with the mission of mentoring foster youth that have aged out of the system or are about to.

When she is not playing the role of mom or mentor she enjoys helping to manage the ranch she lives on where cow, turkey, ducks and chickens are raised. You can also, occasionally, find her at birthday parties or festivals where she works as professional body painter/henna artist/entertainer.

Angelica is extremely excited to begin her career in Real Estate and confident that, with her 15+ years in customer service, her ability to communicate in multiple languages and her natural desire to help others, she can provide a pleasant home buying/selling experience and looks forward to doing so.
