Kay Younggren, DDS


After graduating at Artesia High School in 1998, I continued my education at McMurry University where I receive my Bachelor of Science in Biochemistry with a minor in biology. It was there that my desire to be a dentist began. After graduating from McMurry in 2002, I studied and received my DDS from Baylor College of Dentistry, Texas A&M Health Science Center in 2006. After graduation, I returned to my home town and started practicing dentistry in 2006 at Smile Xpressions. I then purchased the dental practice in 2008 that now has fifteen staff members. I recently built a new state of the art facility for the dental practice that was featured in the Sidekick Dental Magazine in 2017. I am an active member of the American Dental Association including being on the New Mexico Dental Association Board and serving as the Eastern New Mexico Dental Association president. In 2016, I received and completed a fellowship in implantology with the International Congress of Oral Implantologists.

I have served on the Alumni Association Board of Directors at McMurry University from 2008 to 2017. I was also one of the recipients of the first Spirit of McMurry award (the equivalent of the Distinguished Alumni award for alumni under 40). The community of Artesia is important to me and so I have committed to be involved. I’m a member of the Artesia Downtown Lions Club and have been active for the past 11 years. Currently I serve as the co-chair of Jr. Lions, a group that encourages high school seniors to be involved in the community. I’m also on the Artesia Lions Club board and was a recent past president. I’m an Artesia First United Methodist Church member and have served in numerous positions. Additionally, I’m an active volunteer for the local council of the Boy Scouts of America.

When I’m not serving others, you can find me enjoying my time with my family in the mountains or at home with my “furbabies”, my two Biewers Terriers, Gabby and Thunder.

Katelyn Gunn, DDS


Dr. Gunn grew up on an alfalfa farm in Ft. Sumner, New Mexico. She attended West Texas A & M in Canyon, Texas and received her Bachelors of Science in Biochemistry. Dr. Gunn continued her education at Midwestern College of Dental Medicine in Glendale Arizona achieving her Doctorate of Dental Medicine in May of 2018. While at Midwestern, she was recognized as the “Student of Service” for the Class of 2018 which is appointed by the faculty.

She plans to marry to Hunter Buckles of Amarillo, Texas in September of 2018. He constantly reminds her that its okay to not have every detail of every day PLANNED. They are excited to start their life together in Artesia.

Dr. Gunn loves people and comfortably providing a service to both children and adults. She also enjoys the challenges and inconsistencies that dentistry presents.

In her free time, she enjoys cooking/baking, browsing Hobby Lobby/Crafting, gardening, snow skiing, hiking, church events and spending time with her family. You can always find her in the kitchen with her sister, grandmothers and cousins. She admits to being quite the competitor when it comes to playing “forty-two” (dominos).

Dr. Gunn is excited to become part of the team at Smile Xpressions and looks forward to meeting and serving the community of Artesia and the surrounding areas.

Donna Fletcher

Front Desk
I am proud to be a family member of Smile Xpressions since April 2001. I say family because we, the staff and Doctor, not only work together, but pray, eat and socialize. I am the Case Management & Insurance Coordinator: in short, I interview you as a new patient when you first visit our office. Because we believe in ideal treatment planning, I try to find the best financing available for you and your needs. The most challenging part of my job is making sure that you get the insurance benefits you are entitled to.

I am blessed with an amazing husband Marty, and have three children Lindsay, Tommy and Conner. Lindsay has blessed us with a wonderful son in law, Anthony and two fun loving grandchildren, Jacob and Darren, and are expecting twins at the end of 2017.

I enjoy spending time with my family and friends. I am a member of the Eddy County Shooting Range and love shooting a few rounds of sporting clays with family and friends.

I look forward to seeing you in our office.
