I am serving my first elected four-year term as Probate Judge for Grant County from January 1, 2019 through December 31, 2022. I ran for office because I like to help people. I have been a public servant for over 40 years. It is extremely rewarding when at the end of the day you feel you have helped someone with a problem and allowed them to be in a better place than where they were before you assisted them.

I am no stranger to County Government. I started working at the age of 20, way back on January 9, 1978 for the County Clerk’s Office. I was there for eighteen years working myself up as 9th Deputy County Clerk to serving two terms as County Clerk.

I worked diligently and learned all that I possibly could and attended all trainings I could possibly attend. After the Clerk’s Office I worked six years as executive assistant to the Grant County Road Superintendent. This job was fascinating and extremely fast pace and a whole different world to me; I loved it. The position of Executive Secretary to the Grant County Manager came open in the County Manager’s Office, so I applied. I served in that position for three years, talking about fast pace, that office was always buzzing and busy. While working in the Manager’s Office I was asked to go back and serve for a four-month duration in the County Clerk’s Offices as County Clerk. That is where I retired with twenty-seven years of service to Grant County.

In 2006 I ran for Grant County Commissioner District 1 for a four-year term. I became the first woman to be elected Commissioner in Grant County. During this period, I became the County’s Representative on the New Mexico Association of Counties Board of Directors.  While in this position I got elected as President to the NMAC Board of Directors.

My passion, as you can see, is to serve. I truly believe “In order to lead you must learn to serve first.”  Thank you, Grant County, for allowing me to work for you.  I feel blessed and honored.
