Daedra Powers

Hi! I’m Daedra, Dr. Gardner’s Registered Dental Hygienist. I currently reside in Griffon Country (Go Griffs), but I couldn’t be happier to work in Bearcat Country! I enjoy the one-big-family-like atmosphere Maryville has. I began working for Dr. Gardner in 2012 shortly after I graduated for Dental Hygiene from North Central Missouri College. I also attended MWSU and Hawaii Pacific before I settled with NCMC. When I’m not working I love hanging out with my husband, Brad, and my friends and family! I adore my nephew, Joel and we often bond when we get our teeth cleaned together! I truly enjoy working in Maryville and for Dr. Gardner and I look forward to working with you and helping you keep your teeth healthy and clean!



Hanna Strough

Hi, I’m Hanna. I was born and raised in Skidmore! Yes, Skidmore, the town everyone talks about! I now live in rural Burlington Junction, where my husband and I have built our beautiful home. We have a three year old gorgeous baby girl, Taylor, who is full of life and so smart. Away from working part-time, I am a stay-at-home mom, keeping up with Taylor’s everyday adventures, and riding horses. 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 recently became a Certified Dental Assistant.  I am excited to see Gardner Family Dentistry expand and grow with the community. Hope to see you all in the near future!

Hi! My name is Casey, I have been a part of the Gardner Family Dentistry team since February 2016 and I am enjoying all there is to being a Dental Assistant. I was born and raised in Maryville, MO and I attended NWMSU for college. I graduated with a Bachelor of Science in Psychology in May 2015. I wasn't sure what I wanted to do when I graduated until I came across this great opportunity and I have loved it ever since. In my spare time I enjoy doing freelance makeup artistry and hanging out with my friends, family, and boyfriend; Spencer. I am honored to be a part of such a great team and working alongside Dr. Gardner. I look forward to seeing you in the office and getting to know you! 




Danielle Guthrie

Hi! I'm Danielle, one of Dr. Gardner's Register Dental Hygienist! I grew up in Bedford, IA and graduated from Bedford High School. I always knew throughout high school that I wanted to join the dental field as my career. After high school, I attended Des Moines Area Community College, where I took classes to get into the Dental Hygiene Program. During my waiting period of getting into the program, I was a Dental Assistant for 2 1/2 years and also achieved a Business Administration Degree. After starting the hygiene program in 2014, I graduated in May 2016 and have been practicing in both Iowa and Missouri since then. I have been working for Dr. Gardner since October 2016. I had the pleasure of marrying my husband Jason in March 2017 and welcomed a baby girl in March 2018 named Blaire. When I'm not working, I enjoy hanging out with friends and family and golfing with my husband. We both love being residents of Maryville and plan to make this home. Gardner Family Dentistry is a great place to work and a great team of dental professionals. I hope to meet you soon and be able to help with your overall oral health!
