Shawn Tatman



Shawn Tatman

Dr. Tatman was born born and raised in Wyoming. Shawn attended the University of Wyoming, followed by Texas A&M where he graduated from their College of Veterinary Medicine in 2007.  He then completed an equine internship at Anoka Equine, an equine referral hospital in Minnesota.  He returned to his home state and worked at a mixed animal practice until opening Foothills Veterinary Services in 2014.  Shawn enjoys working with the area’s equine and bovine clientele. He welcomes the chance to be outdoors and considers himself an average hunter, poor roper, and an awful golfer.  He also values the time he spends with his future wife, Sarah who has been his greatest supporter.

Foothills Veterinary Service’s  livestock consultant Tammy Gorzalka graduated from the Wyoming School of Animal Technology in 1978. She then went to work for Dr. Lance and Sue Moxey in 1979, where she broadened her strong interest in the livestock industry.  Over the years, she has developed a valuable knowledge base of vaccine programs and has been instrumental in insuring the health of the area’s herds.  She is available to tailor a program for your herd and strives to keep producers informed of new products and opportunities.  Tammy is a vital link between our veterinarian and ranchers, providing valuable information with a smile.  She attempts to garden yearly and loves to can, fish, watch team roping and be outside. However, Tammy’s family is her number one love. She married her husband Lenard in 1980 they have two daughters and grandchildren that are the center of her world.
