I have been involved in the animal health industry for over 20 years in several different capacities. I have worked for the animal health divisions of major pharmaceutical companies such as Schering-Plough, Elanco, and Novartis. I have also worked for buying groups such as Agrilabs. I was also involved in the distribution side of the industry in my 6 years at Waldo/AHI where I was not only the salesman but also the division manager. In my career, I have had the pleasure of working with companion and large animal veterinarians. I have also worked in the companion animal, calf ranch production, dairy production, cow calf production, and feedlot production sectors. I am looking forward to continuing my career here at QMS

I was born in central Minnesota where my family had a small farm, and my love for agriculture stayed the same when we moved to California. We moved to California and my love for agriculture continued. I was active in the Future Farmers of America at John H. Pitman High School, then moved on to California Polytechnic State University at San Luis Obispo, where I earned a Bachelors in Dairy Science. A great part of my job is forming and deepening relationships with my co-workers and clients.

My husband Dennis and I have three beautiful daughters. In our spare time, we enjoy taking the girls to the Oakland Athletic baseball games, the beach, and Portuguese festas.

I graduated from CSU Chico, and a memorable part of my college experience was studying in Nagoya, Japan for a year. During my free time, I enjoy foreign films and documentaries.
