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. 

Hanna Strough, Certified Dental Assistant, Expanded Functions


Hi, I’m Hanna. I was born and raised in Skidmore, MO. I joined Dr. Gardner’s team in 2011 and instantly fell in love with Dental Assisting. I never dreamed I would enjoy educating patients on their teeth, but I love it! I am a Certified Dental Assistant with expanded functions in fixed and removable prosthetics. 

When I am not at the office you can usually find me with my two beautiful daughters Taylor and Chloe. We love to spend our time outdoors being active. I am excited to see Gardner Family Dentistry expand and grow with the community. Hope to see you all in the near future! 

Danielle Guthrie, Registered Dental Hygienist


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.

I had the pleasure of marrying my husband Jason, in March 2017 and we welcomed our daughter in March 2018 named Blaire. We are expecting a baby boy in October of 2021. When I'm not working, I enjoy hanging out with my husband and chasing around my little girl! 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 Impressons"! 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 Mizzou and cooking his favorite meals when he comes home. Katie and I like to try our hand at new recipes, which we test out on the office staff. 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!

Allison Blackford, Front Office Rockstar

Hi! My name is Allison and I have been working with Dr. Gardner since August of 2018. I am originally from southwest Iowa. I first came to Maryville in 2004 where I attended Northwest Missouri State University. I graduated with a degree in Biology/Psychology and have since spent my career in healthcare and technology. Thankfully I am here in a place where I can put both of my passions together! You'll typically find me behind a computer where I'm working to help things run smoothly, as well as throwing in the occasional Facebook post.

When I'm not at work, you can usually find me on the farm with my husband, Cody, and our three boys, Ryker, Maddox, and Dawson. We enjoy raising and showing cattle and pigs, camping, and watching the boys play sports.

I really enjoy getting to know each patient, helping you make the most of your insurance benefits, helping you understand your treatment plans, and getting to the bottom of any question you may have. I love being a part of such a dedicated team, and I look forward to seeing you in the office!
