Ms. PloszajMs. Christy Ploszaj
SPED & Student Support Services Director

I have known that I wanted to be a special education teacher since childhood and have been working in the field of education since I graduated from high school, when I got my first job as a para educator at a school for students with disabilities. After completing my credentialing program, I worked as a special education teacher, educational consultant and inclusive education specialist before becoming an administrator.
It has always been my passion and calling to help all learners reach their fullest potential through the lens of equity, and to be a voice for those who cannot speak for themselves.
I love cooking, camping and spending as much time as possible with my family. I am the proud mom of three adult kids and one beautiful grandson. I also have two awesome step kids and quite a few fur babies!
I am thrilled to join the River Charter Schools team and have been inspired by the compassion and dedication every staff member has for all students and one another.

KamioMs. Kamio Jones
School Psychologist

My name is Ms. Jones. I was born in Ventura, CA but was raised primarily in Sacramento, CA. I attended CSU Long Beach and graduated in 2016 with a B.A. in Psychology and a minor in Africana Studies. I continued my education at University of the Pacific and received my Master of Arts in Education in 2017 and my Ed.S degree in 2020. I am currently in the last stages of finishing up my Educational Doctorate (Ed.D) at UOP. Prior to being hired with River Charter Schools, I worked as a fieldwork student for 2 years in Natomas USD, as an intern in Elk Grove USD for 1 year, and I also was a substitute teacher for Elk Grove USD for 2 years. I was lead down the path of school psychology because I always wanted to work in education since I was a little girl, however I wasn't sure where my place in a school would be best fit. I also had a dream of becoming a child psychologist when I started college. I began to research jobs in psychology and ran across school psychology. The job gave me the ability to work in education and also fulfill my passion to help children in need.  Kamio's Webpage and Kamio's Interactive Office

She hopes to return that to others, always striving to help others make things better for the entire organization.




  Ms. Elena Riolo
HR/Payroll Specialist

I was lucky enough to be born into a large, loud, loving Italian family. My grandparents set roots down here in the Sacramento valley because it reminded them of Sicily. While growing up our family had a cabin in Lake Tahoe and I consider this my second home. Graduated from Sacramento High School and Consumes River College and then entered the business world until I started my family. That’s when I became the CFO/CEO of our family, toughest and best job ever. During this time I worked 9 years for a company processing accounts payable and payroll. I have 3 smart, beautiful and strongly independent adult daughters who are out in the world helping make it better. As lucky as I was before with my family I now have a new family here at River Charter Schools.




CCMs. Chouang Chang
Business Technician

I worked for a private consulting firm as an administrative assistant as well as a supervisor for a café while obtaining my Business Management and Economics degree. After graduating from the University of California Merced, I joined a medical claims team for a business service company and worked as a transaction processor. During my time there, I had the opportunity to acquire and understand many different medical management platforms. Not only, utilizing and developing some of the skills I have today. It was not until later; I discovered my passion and support for education and started looking for other opportunities. Luckily enough, I was given a chance to join the River Charter School team as a business technician where I support the business services department in many areas. It has genuinely been a remarkable journey working with River Charter Schools as I hope to continue my support and inspire others in education.

 Ms. Aristea Walker
Manager of Information Technology

As a Communications Specialist in the United States Air Force I trained in many facets of Information Technology. It was during my enlistment that I realized my passion for technology and the value of teamwork. My thirst for knowledge led me to receiving many industry leading certification such as CompTIA A+, Microsoft MCP, and MCSA as well as degrees in Information Technology and Management. I hope to inspire our young leaders and scholars to think outside box and to view technology as a puzzle that can be solved.
