Intermountain Embryonics was started by veterinarians Hoyt Rees and Rebecca Holmbeck in June of 2017. Both have worked as veterinarians in the Magic Valley for several years and are deeply rooted in the success of the area's animal agriculture industry. Now that IVF technology has become affordable and efficient, it is Intermountain Embryonic's goal to help beef and dairy producers capitalize on this technology. Through rapid genetic improvement that embryo use can provide, producers can increase production rates, improve animal health traits, and increase feed efficiency.

Mobile Embryo Transfer

Genetically superior animals can produce more with less. This helps to make animal agriculture more sustainable and more profitable, while reducing stress on the environment and feeding more people.

Genetic Consultant 


Eric Evans recently joined the Intermountain Embryonics team as our Genetic Consultant and Program Coordinator. Eric will primarily be responsible for designing custom IVF programs on our client’s farms based on specific needs on their operation. He has successfully utilized embryos and IVF on his dairy for many years and brings a plethora of knowledge and experience to our team.

Eric grew up in upstate New York, where he started his career in the dairy industry on his family dairy, Evans Family Farm. Since then, Eric has gained experience with managing an A.I. business, running a mobile hoof trimming truck, dairy herd management, and owning a mineral business in Idaho.

Eric, his wife Misty, and their children currently reside on the family dairy in Buhl, Idaho, Evans Dairy. Their herd is a nationally known registered Holstein and Jersey cow dairy that successfully utilizes IVF to genetically advance their herd. Eric is a self-proclaimed genetic junkie, so he breeds and shows registered Rottweilers and dairy cows as a hobby with his kids. Eric and Misty also have their own cheese-making business in the Magic Valley.
