Suncook Valley Genetics

Welcome to Suncook Valley Genetics. My Name is Steve Marston and I specialize in artificial insemination on cows, pregnancy checks, and embryo transfers. I have been working at our family dairy farm-Marston Farm,  since I could walk. Once in college I became interested in artificial insemination and embryo work. After taking all the classes, I went right to work completing all the genetics on our farm. I have been doing artificial insemination for over 15 years.   I also am a dealer for semen and sell semen for a variety of breeds including Holstein, Jersey, Angus, Wagyu and more.
