Dental Assistant


My name is Khadijah Mckinney, I’m 23 years old and I currently work as an Expanded Functions Dental Assistant here at River Oak Dental. My interest in dentistry sparked around the age of 10, having wearing braces for the majority of my childhood and teens, I found myself becoming more and more intrigued with dentistry, which eventually led me to pursue a career in the field.

In my spare time, I like spending quality time with my mother Brenda and older sister Ashley. Our favorite thing to do as a family is to watch Family Feud together, trying to guess all the number one answers. I am also a bit of a book worm and tend to always have my nose in a really good mystery or sci-fi book.

As of today, my personal main goal as an assistant is to help you maintain and achieve your ideal smile, as well as provide you the comfort and care during your dental treatment, which I feel is just as important as the treatment itself.

I fully believe that everyone can achieve their optimal smile, my job is just to help you along the way, the best way I can.

In her spare time she enjoys traveling with her husband and spending quality time with their daughter.

Kaitlynne has been part of our team since 2017. She has been drawn to beautiful smiles since she was 6. She has a passion in making sure our patients can achieve a healthy and “sparkly” smile. Kaitlynne received a Bachelor of Science from University of Central Florida in Health Services Administration and an Associate of Science from Eastern Florida State in Dental Hygiene. She grew up in a military family which is a big reason why she loves travel and adventures. She has 2 wonderful children, Brooklynne and Brantley. She is a hard-working mommy with a dedicated soul and loves to make time for beach days, enjoying local spots for some grub.

Office Manager


My name is Liz Prentice and it has been my privilege to be part of the River Oak Team since 2015. I started my path to dentistry as a paralegal, where I found the most joy when I was helping patients get well and healthy; and that led me to my career in dentistry over 10 years ago. If I wasn’t in dentistry, I’d love to have studied Ornithology and work for the Audubon Society.

I grew up in Dover, Delaware and moved to Florida for college, where I met my husband, John. I am a lifelong Philadelphia Eagles fan. I enjoy cooking at home and working out, and if it’s not a football Sunday, my husband and I spend our free time boating to the inlet and stand up paddle boarding. We have a pet lovebird named Boo, who travels with us everywhere we go.
