Daedra Powers, Registered Dental Hygienist 

Hi! I'm Daedra (pronounced Day-dra) and I have been a hygienist for Dr. Gardner since 2012. I always knew I wanted to be involved in a dental office as I had loved going to the dentist as a kid. I graduated with a degree in dental hygiene from NCMC. You will find me behind the scenes cleaning teeth and making people smile. 

When I'm not at work, you can find me running around St. Joseph with my husband, Brad, and our little boy, Carter. We enjoy cheering on the Chiefs and Royals, being outside, traveling and watching Carter play t-ball. 

Danielle Guthrie, Registered Dental Hygienist, Expanded functions


Hi! I'm Danielle, one of Dr. Gardner's Registered Dental Hygienists! I grew up in Bedford, IA and graduated from Bedford High School. After high school, I attended Des Moines Area Community College where I took my general education courses to get into the hygiene program. During my waiting period of getting into the program, I was a dental assistant for 2 years. I graduated in May of 2016 and I practiced in Iowa until starting with Dr. Gardner in October 2016. In 2021, I expanded my knowledge and completed my certification for restorative in March 2021. 

I had the pleasure of marrying my husband Jason, in March 2017 and we welcomed our daughter in March 2018 named Blaire. Our son Rylan completed our beautiful family in September 2021. When I'm not working, I enjoy hanging out with my husband and chasing around our two beautiful children! Gardner Family Dentistry is a great place to work and we have a great team of dental professionals. I hope to meet you soon and be able to help with your overall oral health.

Darchelle Gardner, Office Manager

Hi! My name is Darchelle. I wear many hats in the office including Office Manager, Dr. Gardner's wife, and "Office Mom". After 22 years as a cardiac nurse, I made the decision to join Jeff in the office. I am usually up in front answering phones and I have come to enjoy the title of "Director of First Impressions"! After 22 years of direct patient care, I do enjoy assisting in the back as well.


In my spare time, I enjoy visiting Alex at UMKC School of Dentistry and cooking his favorite meals when he comes home. Katie graduated in May 2023, with a degree in Business and Accounting from Oklahoma! Our family enjoys spending time at our farm with our two dogs: Jag, the Brittany and Willow, who is a Wirehaired Pointing Griffon. We also enjoy traveling as a family and visiting new destinations.

Jeff and I feel passionately about the organizations that we support including Big Brothers Big Sisters, Countryside Christian Church, Missouri Mission of Mercy (MOMOM) and the Belize Mission Project. Each year we make it a point to close the office to attend MOMOM and donate our time to provide free dental care to those in need. In October of 2018, Katie and I were blessed to be able to go on the Belize Mission Project where we were part of a team that provided dental services including restorations, extractions, and preventative care to the under-served people of Belize.

I enjoy working in the office, visiting with people, and being witness to Dr. Gardner and the staff provide exceptional patient care. Please make sure to say hi when you're in the office!

Jordan Schieber, Dental Assistant 


Hi ya'll! I'm Jordan, I am a dental assistant here at Gardner Family Dentistry. I grew up here in Maryville, attended college at Northwest, then moved up to Iowa shortly after I graduated. There I was a Registered Dental Assistant for about 3.5 years. When I moved back to town I took a year off to explore other options and found myself missing the dental life. So now, here I am!

Outside of work, I am usually spending time with my doggo and my husband, Brad, who I married on Halloween weekend of 2022! We welcomed our first child in August of 2023, and she is such a blessing and it is so fun to see her grow! We enjoy going down to the Lake of the Ozarks and spending time with family. 

I enjoy working along side the amazing team here at Gardner Family Dentistry and enjoy helping our patients love their smile!
