Executive Administrative Assistant

Welcome to Collaborative Psychology Group!

My name is Taryn Sherrill and I am the Operations Manager here at CPG. I began my journey at CPG in 2015 as the receptionist for the practice, and grew to become the Administrative Assistant until 2019. My experience at CPG planted the seed for my passion and love for mental health. I carried that passion with me after I left CPG in 2019, and I decided that this is the field I wanted to be in. In 2021, I began my education at Riverside City College where I earned my associates degree in psychology in June of 2024, and am currently earning my BSW at a Cal State.

I'm Cheyienne, I've been in the medical field for many years, from assisted living facilities, to working with a nonprofit organization, housing the homeless and Veterans. I'm blessed to have the opportunity to work with the Collaborative Psychology Group. I'm excited to learn more, and assist the community, in any way I can. I'm a mother of 2 amazing children, and outside of work, I'm dedicated to them, and all their activities. I'm a dedicated worker, and a strong team player, I am willing to help when needed, no questions asked. In my spare time I enjoy spending quality time with my children and family, I love to shop, for myself and others, I'm very much a giver, it fills my bucket! I'm excited on my new Journey in life, and to see what life has in store for me and CPG.

I am a recent recipient of RCC's Certificate of Completion-Interpreting Training Program; I look forward to continuing on in my educational journey in hopes to take part in RCC's first-ever Bachelor's Degree Program for Interpreting.

As a CODA I am humbled to take part in this momentous ground-break between the Deaf Community and the field of Mental Health for Riverside County.

Billing

Brittni

Medical Biller

Hello, my name is Brittni and I am the medical biller here at CPG. I specialize in medical billing and truly enjoy what I do. I am also a wife and a mother, and I wouldn’t change that for anything in the world. I enjoy working at CPG and consider myself a very understanding person, which helps me greatly in my role as a biller. I understand that the current economy makes financing difficult for many people. While CPG is a business, I strive to make our clients feel comfortable when discussing their accounts. If I could improve the world, I would make healthcare more accessible to a larger population. For now, I take small steps whenever I can to do my part in making the world a better place.
