Taryn
Director of Operations​
Welcome to Collaborative Psychology Group! My name is Taryn Sherrill and I am the Director of Operations here at CPG. I began my journey at CPG in 2015 as the receptionist for the practice, and shortly thereafter I was promoted to 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. I recently accepted admission into CSUSB for their BSW program and am excited to start in Fall of 2025.
In addition to going to school during my time away, I was a stay at home mom to my three amazing children! We are a sports family and love going to flag football and soccer games. We also love going to the movies, the beach, and spending time with our families.
Being back here at CPG feels like being back home. It is important to me to maintain an environment that makes you feel welcome when you step into our offices. As the Operations Director here at CPG, I am confident in my ability to help you in any way I can with the upmost respect, compassion, empathy, and privacy. I am so exited to be back, and I look forward to assisting you!
