Dakota Keipert

HR Specialist

Though this is Dakota’s first time officially working in the Human Resource field, she strives to learn as much as she can, as soon as she can. Her goal is to find solutions to the problems she is presented with and to provide clear guidance to those who need it.

Right after high school, Dakota took an ambitious route and studied abroad at Franklin College in Switzerland, where she took the opportunity to see parts of the world. She worked with Habitat of Humanities fixing up old homes in Poland which would eventually become safe places for children. She attended the biggest festival in Munich, Germany, and enjoyed the many diversities Oktoberfest had to offer. And when not attending classes, she could be found in the markets in northern Italy or on the basketball court.

After returning from her oversea studies, Dakota decided to complete her Associates degree in Art from Chandler-Gilbert Community College. She has completed courses from Geology, Communications, Psychology, Ceramics, to Native American Religions, Law Enforcement, Anthropology and Art History. Dakota does plan on returning to school to complete her Bachelor’s degree, but in which field, has yet to be decided.

Dakota has been involved in her community from a very small age. Her father, being a police officer, was always volunteering, and instilling the values of a safe, healthy community. She was/is involved in Boy/Girl Scouts, Community Activities; such as Arizona’s Ostrich Festival, Chandler Tactical Competition for Cadets, Cooking meal after meal for the S.W.A.T. Team, and much, much more. She was raised with excellent morals and ethics to naturally do the right thing, and to be a good person.

Dakota is a wife to a Veteran Marine. Through her relationship, she has utilized her teachings of self-sacrifice, dedication, loyalty, adventure, and compromise. In October 2018, Dakota became a mother to a beautiful, adventurous, and loving daughter. She loves the saying, “the heart does not have a limit on love, but will simply grow to make room for more,” and hopes to also continue growing her family.
