Chele Pint

Medical Biller/Credentialing Specialist

Chele Pint’s two favorite kind of days in Bozeman are a clear blue-sky with white snowcapped mountains surrounding the valley and a warm summer night around the fire with friends after an amazing day of boating!

As a certified medical billing and credentialing specialist she has been working in the Autism world for the past 6 years and loving it.  Prior to this, she worked at the Cozy Nest and a life time ago she was a Respiratory Therapist.

Chele moved to Bozeman 16 years ago with her Husband and two kids, who are now a Junior in High School and a Freshman in college, which seems impossible since she is only 20…..okay…….30……..fine…….40(but that’s as high as she is going!) She spends lots of time outdoors doing all the ing’s: skiing, biking, camping, gardening, boating to name a few.

olivia Mccafferty


I am originally from Moses Lake, Washington. I moved to Montana a day before my first day of high school in Belt, Montana, where I lived with my mom and brother on our cattle ranch. After I graduated I moved to Missoula and was enrolled in elementary education for two years at the University. I realized I was more interested in Psychology and currently have two more semesters before I graduate with my bachelors in Psychology this spring. I wanted to work at Peach Tree because I think this line of work is very rewarding and I am excited for a new experience from previously working for adults with autism.RBT
