Tyra Miller

Tyra has over 20 years of experience as a paralegal and is Board Certified in Family Law by the Texas Board of Legal Specialization. She earned her bachelor’s degree from The University of North Texas in 1997. Tyra lives in Frisco with her husband and daughter and their two Pugs.

Tyra loves assisting individuals and families. Including teaching and empowering children to become the best they can be. Guiding each person through what is, most likely, the most challenging time in their lives by arming them with the tools they need for success once their legal case is over. Change is difficult and when clients emerge from the valley they were in at the time our services were initiated, it’s important for them to know that life continues, and that we have ensured that they feel confident navigating the new terrain they now face with optimism.

  • Board Certified Family Law Paralegal - a para for almost 22 years (August will be 22 years)
  • Bachelor's degree from UNT in 1997
  • Love working with students/children - collaborating with them to teach, encourage, and empower them to be their best selves
  • Love helping people and families - helping guide clients through a challenging time in their life and arming them with the tools they need once their case is over. Life happens after their case is closed - so it's important to think about that when helping them go through the valley they are trying to climb out of when they hire us
