Sloane Ault

Dental Hygienist

Growing up, I moved around quite a bit, mostly between Oregon and Washington, but ended up in our wonderful state of Montana. In 2009, I graduated from Columbus High School and immediately pursued my lifelong goal to become a dental hygienist. Due to a very traumatic experience, I am deathly afraid of the dentist! Having dental anxiety myself is what motivated me to pursue this career choice. I wanted the chance and ability to diminish those fears in my own patients by providing them with insight and understanding.

I attended the Sheridan College dental hygiene program where I earned my Associate of Science in dental hygiene. In May 2015 I earned my Bachelor of Science in dental hygiene through the University of Wyoming. I feel very happy about having the opportunity to help people in this line of healthcare. I love getting to know my patients and helping them understand their oral health needs. I’m hoping here at BSSC I can continue to educate patients about oral health as well as make them feel comfortable each and every time they step through our doors.

I moved to Miles City in the winter of 2015, and I’ve loved every minute so far. I enjoy spending time outside with my little dog Mollie, who is a mutt full of energy and love. She keeps me busy and on my toes at all times. I also like going on hikes, riding horses, playing all kinds of sports, shooting guns, camping, and pretty much anything to do with the great outdoors. Another goal I’d like to accomplish in the near future is to coach either volleyball or basketball here in Miles City.


Kristi Certain

Dental Assistant

I was born and raised in Glasgow, Montana and lived there for 20 years. I moved to Miles City in August 2005 to attend MCC and pursue a career in nursing, but I quickly learned that nursing was not where my heart or passion was. I started working at Big Sky Smile Center in March 2008. I love my job and all that I have learned over the years; I learn something new each day. I couldn’t ask for a better way to spend my day than with my second family!

On September 17, 2011, I married my best friend, Ben Certain. We quickly learned that we were not complete and wanted to start a family right away! In January 2013 we welcomed the arrival of our sweet baby girl, Ella Grace! Now two, she constantly keeps us busy. It’s amazing to watch her learn and grow each day! We still have our dog, Maya. She is so good with Ella! They roll around on the floor together, cuddle on the couch, and watch movies on occasion. They love to be outside running around, and Ella might slip her a snack here and there when Mom and Dad aren’t watching!

I’m excited to see our office change and grow with the addition of several new team members. I’m glad to be a part of this journey and I hope you are too!


Kami Montgomery

Dental Assistant

I’m a proud native Eastern Montana girl! I was born and raised in Miles City, and moved between Rosebud and Miles City while growing up. I graduated from CCDHS in 2009 and went off to college in Sheridan, Wyoming. I had originally planned on attending their dental hygiene program, but I decided to move back to the place I love, Miles City, to be closer to my family.  

In 2011, my son Gabe was born. He is full of joy and personality! Then, in 2013, I added a little girl to the mix: Kendall. She is beautiful and it is so much fun watching her grow! I am very blessed to have such a wonderful family!

I worked in the banking industry for the past few years, but have always had an interest in the dental field! I am so grateful for the opportunity to better myself and others at Big Sky Smile Center. I hope to see you in our office soon!


Kodi Malnaa

Dental Assistant

I was born and raised in Glasgow and moved to Miles City in 2010. In 2012, I was blessed with the arrival of my amazing son, Traeven. He has brought me so much excitement from the word “go,” and keeps me very busy with his enthusiasm for anything sports or horse related! When we have free time, we enjoy golfing, fishing, traveling, watching almost any sporting event, anything involving horses/the western way of life, and just being outside enjoying the beauty that Eastern Montana has to offer! 

My passion has always been helping others in any way I can. I am so excited to be a part of the Big Sky Smile Center team and to be a part of a group of professionals that share the same passion that I do! I look forward to meeting you and providing you with a dental experience that will exceed your expectations!


Katie Adams

Scheduling Coordinator

I joined the amazing team at Big Sky Smile Center in August 2013 as a part-time dental assistant until May 2014 when I transitioned into the new full-time position of scheduling coordinator! I’ve worked in the dental field now for eight years, knowing from day one it was the career for me! For five years I worked as a dental assistant in Wyoming and loved every minute of it. So naturally, coordinating the schedule to ensure staff and patients have the ideal dental day was my “cup of tea”!

My wonderful husband, Sam Adams, and I were both born and raised in North Central Wyoming. We both have a passion for music and love being outdoors for any reason: camping, hiking, fishing, golfing, or just sitting around a nice fire with good friends. Needless to say, moving to Montana was a very easy transition!

I am so glad to be a part of BSSC and of Miles City. Every day I get to work and grow with an amazing group of dental professionals that make you feel part of a true dental family! I look forward to meeting you all and providing the best dental experience, from the moment you call to the moment you are waving goodbye with that beautiful BSSC smile!

Kristie Wright

Office Manager


I was born and raised in Bozeman and graduated from Montana State University in 2003 in health and human development. I started my career as a case manager for adults with mental disabilities before being offered a position in 2007 at Bozeman Dental as office manager. I worked there for five wonderful years before moving to Miles City with my husband Travis.

We moved for my husband’s career with Stockman Bank, where I also worked for three years, until I was given an opportunity to join the amazing crew at Big Sky Smile Center. I am so fortunate to work with such great people and look forward to working many years with this amazing team!


Lindsey Menyhart

Operations Manager

I was born and raised in Missoula. I attended the University of Montana and have a BA in psychology, with a minor in human and family development.  To say I'm a Griz fan is a major understatement!  My family and I moved to Miles City several years ago and we are happy to call Eastern Montana home!  Life is busy with two children and we enjoy traveling, eating great food, jumping on the trampoline, watching football, riding our bikes, and having movie nights with stove-top popcorn!!  

I joined the team at Big Sky Smile Center in 2012. I am very blessed to be a part of the {AMAZING} BSSC family! I have learned so much since I started a career in dentistry, in which I knew very little!, and in September of 2017, I was the first Montanan to earn the title of Fellow of the American Association of Dental Office Management!  At BSSC, we never stop learning and evolving and I'm so excited to continue to grow in my professional role!  I look forward to helping our team exceed your expectations about “going to the dentist,” and making your dental experience at Big Sky Smile Center an enjoyable one!
