Meet Our Therapists
At Fuller Psychological and Family Services (FPFS), we provide professional counseling and assessment services through a collaborative team of clinicians at different stages of their professional journey. Our approach combines academic excellence, clinical expertise, and compassionate care. Every therapist—licensed, advanced, or in training—is committed to helping clients achieve emotional, relational, and spiritual growth.
Licensed Professional Therapists
FPFS employs on-site therapists who are licensed as either Marriage and Family Therapists or Clinical Psychologists. These licensed professionals bring years of experience and advanced training to their work. In addition to providing therapy and assessment services, they also supervise Advanced (Degreed) Therapists and Graduate Student Trainees, ensuring that clients receive high-quality care and that future clinicians are well-trained and supported.

Advanced (Degreed) Therapists
Advanced (Degreed) Therapists have completed a master’s or doctoral degree in Marriage and Family Therapy or Clinical Psychology but are still accruing the supervised hours required for licensure. They have already completed extensive clinical training and provide therapy under the supervision of licensed professionals. This model allows clients to access expert care at a more affordable rate while helping clinicians deepen their skills and experience.
