Recently was a part of a successful lobbying effort in 2019 to pass into law a major energy transition legislation for renewable energy development across the state that's become one of the top national models, also helped pass updated oil and gas industry laws, successfully passed Scope of Practice legislation in 2017 for a healthcare client (which is no easy task in NM), assisted a racing-industry client in strengthening regulations regarding illegal drug use and tax protections.

I was born and reared in Albuquerque, New Mexico and received my college education at the University of New Mexico. My father was a State Representative in the 70's and was a lobbyist for 37 years until his retirement in 2016, so New Mexico politics has been a big part of my family for a long time. My father started bringing me and my brother to the capitol when we were toddlers where I got to watch him in action and learn how things work at the legislature; and more importantly, how to talk and connect with people. Through many years of following my dad around the capitol and traveling with him around the state for work, I was able to receive a comprehensive, but also intimate education in politics, legislative affairs and the unique inner-workings of the political environment of New Mexico. This experience prepared me to be able to work effectively in the family business for the last few years of my dads career and
successfully carry on the business when he retired in 2016. I've also been successful in obtaining my own clients and working on a variety of important issues in the state ranging from healthcare to energy policy. I'm proud to have a solid reputation as an effective and trustworthy lobbyist and I enjoy advocating for my clients and helping them reach their legislative and regulatory goals.
