Hi, Im Cassondra Del Rosario or Cassie is a Licensed Professional Clinical Counselor. I have a Master’s Degree in Developmental Psychology from Azusa Pacific University and a Master’s Degree in Clinical Counseling from Alliant International University. I am trained in EMDR to support and help those heal from their trauma.
I am a board certified, doctoral prepared PMHNP. I completed my post graduate at National University in Adult, Child and Adolescent Psychiatry. I earned my DNP from Azusa Pacific University and graduated from CSUSB MSN program. I have been a faculty at CSUSB since 2014. Extensively trained and a certified Trauma-Informed specialist. I diagnose and treat mental disorders including medication-assisted treatment along with counseling for chemical dependency and substance use disorders.
My approach is collaborative, compassionate, and practical. I pull from cognitive-behavioral therapy (CBT) to help you understand patterns in your thoughts, feelings, and behaviors, but I also lean into a humanistic style, meaning I see you as a whole person, not just a diagnosis or a set of symptoms.
I believe therapy should feel like a safe, judgment-free space where you can show up as you are. Whether we’re exploring your relationships, working through anxiety or depression, or identifying what really matters to you, my goal is to support your growth with curiosity, care, and clarity.
I also value realness, I’ll challenge you when it’s helpful, offer insight when you're stuck, and celebrate the progress you might overlook. You're the expert on your life; I’m here to help you reconnect with that truth and build the kind of change that lasts.
