With several homes in the works, the Artisan Homes team is eager to share its love for building

Tammy Doyel is the kind of gal who greets everyone she meets with a warm smile and a “can-do” attitude. She’s learned the art of impeccable customer service during her past eight years working as a real estate agent. Tammy is currently employed with Keller Williams Siouxland in Sioux City. She also loves the building industry and, as a REALTOR®, Tammy has almost 100 custom homes under her belt. With her new role at Artisan Homes, Tammy looks forward to combining all her passions to help people settle into their dream homes.

Tammy hails from Humbolt, Iowa. She graduated from high school in 1985, then went to beauty school for her cosmetology license. She was an instructor, clinic floor director and recruitment specialist for La’ James College of Hair Design, and owned salons and medical spas in the Sioux City area for 25 years. Tammy became a real estate agent when she was in her early 40s, initially selling for RE/MAX, then joining Century 21.

She’s also raised a family, calling herself good friends with her children Parker, 26; Hannah, 25; and Levi, 20. Naturally, she adores spoiling her granddaughters Jaylin, 5; and Kinley, 7 months old.


When she’s not working, Tammy loves traveling, especially to the Florida Keys. She also enjoys movies, fitness, nutrition, and spending time outdoors.

What does she like best about her role with Artisan Homes? “I like seeing a plan on paper come to life,” said Tammy. “It’s exciting to be part of that process and an honor for the homeowner to trust us. It’s a forever bond.”
