About Me

Sarah is an Arizona native and has spent her entire life living in the west valley. She is married to her high school sweetheart, Ernest, and has three grown children, Chano, Alycia, and Virginia. Chano is an emergency room nurse at Banner Estrella hospital, Alycia recently graduated from Arizona State University with her Biomedical Sciences degree, and Virginia is in Nursing School through the concurrent enrollment program with Estrella Community College and Arizona State University.

Sarah has dreamed of opening up her own Estate Planning Firm and using her passion to help others by creating advanced plans so people can designate who they want their possessions to go to when they pass, designate who they want to make health and financial decisions if they are unable to do so for themselves, name guardians for their children, help avoid family conflicts, and avoid probate court. She also wants to help families pass on their values, traditions, and family history through life story videos and letters. We often lose the opportunity to ask the really important questions because we think we will live forever and then that opportunity passes us by. Sarah wants to capture all those important memories.  

Sarah retired from a career with the Maricopa County Juvenile Probation Department , the 4th largest county in the United States, where she supervised multiple Divisions and oversaw the Community Supervision Bureau. Sarah used her passion to help youth make positive changes in their lives and create long term success.  


Sarah is an accomplished Deputy Chief Probation Officer with 21 years of progressive experience in juvenile justice and government administration. She was repeatedly recognized for top performance through fast-track promotions and selection to lead high priority initiatives. She has implemented several complex system improvement initiatives including the Crossover Youth Practice Model which improves outcomes of youth involved in both the child welfare and juvenile justice systems. She also brought awareness to victims of sex trafficking by working on a collaborative with other child serving stakeholders, initiating a screening tool to identify youth that was later validated by Arizona State University Office of Sex Trafficking  Intervention Research (STIR),  and creating dedicated caseloads. Sarah was recognized as a collaborative leader who brought together both internal and external juvenile stakeholders to implement juvenile justice reform efforts and developed long term professional relationships.  


She has an extremely diverse background in operations, program development, project management, casework management, budget and procurement, training curriculum development, drafting policy, research and analysis, human resources, and strategic planning. She has a strong knowledge base across a wide array of legal topics.

When Sarah is not working, she enjoys spending time with her family hiking, cooking, watching movies, having game nights, and going on family vacations. Sarah enjoys reading, swimming, and dancing.
