I am the Office Manager for Dunes Dental 4 Kids. I have been working with Dr. Hemmingsen since August 1, 2001, when he opened his practice. When Dr. Howenstein joined the practice, that made our office even better.   I truly love working at Dunes Dental 4 Kids!  We have two great Doctors and  a great staff that helps to comfort and support each patient and educate the parents.  I have made so many friends from the parents that bring their children to our office.  It has been such a joy watching them all grow up.

When I’m not working, I enjoy spending time with my Grandchildren.  They fill my heart with so much love.  My hobbies include quilting, photography,  flower gardening and anything else that might look fun on Pinterest!  I’m a big fan of the Denver Broncos and the Chicago Cubs.


Hi, my name is Nicole.  I’ve been at Dunes Dental 4 Kids since 2007.  There is not a day that goes by that I’m not thankful for my place here at Dunes Dental 4 Kids.  I enjoy working with both the children and their parents.

Outside of the office I enjoy spending time with my husband and daughter.


Hi! I'm Kristin, I first started working for Dunes Dental 4 Kids May 26, 2015. I left the following year to stay home with my newborn daughter. I just recently rejoined the team in March 2017 working Tuesdays and Wednesdays, and couldn't be happier. My husband and I have been blessed with 4 beautiful children that take up ALL of our time. In what spare time we do have, we enjoy doing projects and renovations to our home and having game nights with friends.

Hi, my name is Holly.  I love being a dental hygienist at Dunes Dental 4 Kids. I started my dental career as a dental assistant in a pediatric office in the fall of 2000 in Reno, NV. I have always loved my time working with children and assisting in hospital settings, general offices, and endodontics, which I did until 2011. It has been my goal since I was 12 years old to become a dental hygienist. In 2011, my husband accepted a job as one of the practicing dentists at the Winnebago Tribe of Nebraska's IHS clinic and we moved from Las Vegas, NV to Sioux City in August of that year. We welcomed a son, our first child in December 2012. I decided to pursue a higher education from the University of South Dakota and graduated in 2016 with a Bachelor's degree in Dental Hygiene.

I love spending time with my husband and son. We enjoy being outdoors, going on family bike rides, attending church, having dinner with friends, and it is always a highlight in our life when our family comes to visit us. I am excited to continue my career at Dunes Dental 4 Kids and give the best patient care to our great patients.
