Team Directory


Becky King, Schedule and Financial Coordinator

Hi, I’m Becky. I joined the Cook Becky HeadshotOrthodontics, P.C. team in 2011.
I enjoy assisting patients through all stages of ortho treatment and having the opportunity to see the end results, which is a wonderful smile! I love being in an office where I not only get to work with great people but also get to meet so many awesome new people like you!

In my time away from the office, I enjoy being a mother to my two beautiful daughters, Alexandra and Nicole. I also like to spend quality time with friends and family. Depending on the season, you can find me hanging out beside a pool or cooking s’mores over a campfire! I look forward to meeting you very soon!

Kelly Kain, Treatment Coordinator

Kelly headshotHi! I’m Kelly and I will be taking care of you on your first visit to Cook Orthodontics, P.C. I have been a dental assistant for over 25 years and have worked in many specialties, including pediatrics, general dentistry and oral surgery. I joined the Cook Ortho team in 2009.

I really enjoy working with children as I have three of my own. In my "spare time" I can be found on any given sports field or court watching my kids play their sport of the season. I also enjoy reading, shopping, and traveling when time allows!

I look forward to meeting you at your first appointment!

Deanna Saucerman, Lab Coordinator and Clinical Assistant

Deanna headshotHey everyone! Welcome to the Cook Ortho website! My name is Deanna. I am a clinical assistant as well as the lab coordinator. I make all the cool retainers that you receive at the end of your treatment. I have worked for Dr. Cook since 2008 and I love it! We have a great time and usually act pretty goofy!

I have two daughters that had orthodontic treatment with Dr. Cook, and their smiles are beautiful! I have been a dental assistant for over 24 years. (That’s probably longer than most of you have been alive!) I love what I do. It is so gratifying to see the changes our patients go through during orthodontic treatment.

When I’m not straightening your teeth, I enjoy hanging out with my family and friends. I have two cats named Smokey and Chewy and a snake named Tiny. He’s really not very tiny though! I look forward to meeting you and hope to see you soon!

Rachel Sitterding, Clinical and Scheduling Assistant

Rachel headshotHello! I’m Rachel. You will see me in the clinic as well as helping schedule your next visit. I enjoy the opportunity of getting to know all of our patients and seeing the positive changes in each smile! I graduated in 2006 from USI with an Associate of Science degree in Dental Assisting. I have been part of the Cook Ortho team since 2011.

Outside of work, I enjoy being outdoors, following sports, shopping, traveling, and spending time with family. 


Ashley Kohute, Clinical and Scheduling Assistant

Ashley headshotHi. I'm Ashley. I am so excited to be part of the Cook Ortho team! I graduated from USI's Dental Assisting program and began working for Cook Orthodontics, P.C. in May 2014. I work as a clinical assistant and most likely will put your braces on, take them off and help with all appointments in between. I look forward to meeting you!

A fun fact about me is that I was a cheerleader for the USI Men's basketball team. Stunting is my hobby! In my spare time, I enjoy spending time with friends, shopping and being outdoors.

Beth Buechler, Clinical Assistant

Beth headshotHello. My name is Beth. I have been in orthodontics for over 10 years as a clinical assistant and have worked for Cook Orthodontics, P.C. since January 2015. I love adding humor to the office to help patients feel at ease and enjoy their visits. Laughter is the best medicine! 
Outside the office I enjoy spending time with my two children, Amity and Corbin. Of course I can't leave out Braeley, our miniature Yorkie! I also love going to St. Louis Cardinal games and traveling anywhere south. If I am lucky to assist you in my chair, plan on a few corny jokes and a few laughs along with your appointment. After all, we have to show off that smile!!

Haley Thewes, Clinical Assistant

Haley headshotHi, my name is Haley. I graduated with an Associate of Science in Dental Assisting from the University of Southern Indiana in May of 2017. I joined the Cook Orthodontics team as of January 2018, and I love it! As my part of the team, I assist with chair side procedures like putting on braces, adjustments, and taking braces off. I also work in our lab making retainers. Getting to see my patient’s smile transform is my favorite part about my job! 

I spend my spare time hanging out with friends or visiting my family. I also enjoy spending time out on the lake, jeeping, going to the gym, traveling, and meeting new people!

Whitney Spainhoward, Clinical Assistant

Hi there! I’m Whitney. In 2006,Whitney headshotDr. Cook hired me to work as the Scheduling and Financial Coordinator.  I answered phones, scheduled your appointments, reviewed financial contracts with you, checked on insurance benefits, and so on. In 2016 I took a break to spend extra time with my family.

In 2018, I was fortunate enough that Dr. Cook and the team re-hired me to rejoin the Cook Ortho team. Now, you may find me taking care of your New Patient appointment, removing your braces, or anything in between.

 No two smiles are the same!  I love watching the transition orthodontics makes in each patients’ smile. Both of my children benefited from orthodontic treatment and I can’t wait to see how you benefit as well!

 I have been married to a great man, Darren, since 2002. We enjoy traveling, going to MLB & NBA games, and going on family vacations with our adult children, Alex & Lauren. I also enjoy reading, gardening, and spending time with girlfriends.  We also have a 6 lb Yorkie-Poo named Baxter who thinks he is 76lbs!!!!     

Robin Cook, Office Manager

Robin headshotHi, I’m Robin! I have been working at Cook Orthodontics, P.C. since the opening in September 2003. I work in the business office behind the scenes, performing bookkeeping and payroll duties as well as coordinating our community involvement activities and local team sponsorships.

Currently, I work part-time for Dr. Cook so I can also spend quality time at home with my young son, Carson. In my free time, I like to travel, read, watch movies and spend time outdoors with my family!

I really enjoy the family-friendly atmosphere we offer at Cook Orthodontics, P.C. The people I work with are fabulous, and I’m lucky to have them as both co-workers and friends. Orthodontics is really the best job in the world. We have the opportunity to provide such a positive impact on people! And the best part . . . that smile lasts a lifetime!
