Brittney Neal

Office Manager

My name is Brittney and want to thank you for taking time to learn a little about me. My professional background comes with a variety of different industries including 3rd party logistics, construction,  the entertainment business and mental health, but with each of these there is a basis in customer service. My degree is in Behavioral and Social Sciences and my passion is in helping others find their passion!

In the past, I have volunteered in different areas such as Pop Warner Cheer as a Team Mom & Coach and as an advocate for victims of human trafficking by being involved in an Anti-Human Trafficking group. I believe that public awareness and acknowledgement is very important to ending human trafficking. 

I'm  married, a mom to one daughter and one fur baby. I've achieved attunement to Reiki II, practitioner level and love being able to help others when I can. A few things to know about me are that I enjoy family time, coffee a little bit too much, collecting and using crystals, and doing things with friends.

I'm excited to work with and be a part of  Collaborative Psychology Group!

“Mental health: having enough safe places in your mind for

your thoughts to settle.”
— Alain de Botton

Hi! I’m Kalena. Mental health has always been an important part of my life for many reasons. I’m a kind, compassionate and empathetic person, and I believe that this has guided me to where I am today. I graduated from Platt College in 2016 with an Associate Degree in Medical Administrative Assisting. I have several years of experience with working in the Mental Health field, in both Outpatient and Inpatient facilities. I also worked for County of Riverside for 5 consecutive years but decided to end my journey with the county to join the CPG team. I’m honored to be a part of this team and hope to be a great asset. I look forward to assisting the individuals and families who need it. I love spending time with my friends and family, making and listening to music, going to the beach, being outdoors, thrift shopping, the color green, Korean BBQ, astrology, spirituality, and listening to audiobooks on self-development.
