Meet Our Team
Dr. Gustavo Franza
I am a bilingual Spanish-speaking licensed psychologist in Phoenix specializing in diagnostic, forensic, neuropsychological, neurodevelopmental, and neurocognitive assessment across all age groups. I earned my Doctorate in Clinical Psychology from the Arizona School of Professional Psychology in 2012 and am the founder of Franza Psychological Services.
I conduct evaluations for family, DCS, criminal, immigration, and administrative courts, addressing a wide range of issues including competency, child custody, parenting capacity, mitigation, violence risk, guardianship, disability, diagnostic clarification, expert testimony, and pre-sentence evaluations. My professional background spans private practice, inpatient, and correctional settings, providing the breadth of experience necessary to deliver balanced and comprehensive assessments tailored to each case.
In addition, I work with an elite team of clinicians who provide therapeutic support in areas such as trauma, life transitions, and addictions. Our therapeutic services are highly individualized, designed to meet the unique needs of each client.
Dr. Christina Horner
I have over 10 years of experience providing psychological assessments and therapy for children, adolescents, and adults, and hold a doctorate in Clinical Psychology from Northern Arizona University. I am currently supervised by Dr. Gustavo Franza. I understand that seeking help can be challenging, and I strive to provide a safe and supportive environment as clients navigate difficult life circumstances.
I recognize that negative experiences can influence thoughts, emotions, and self-perception, sometimes leading to patterns and behaviors that affect many areas of life. I help clients identify and challenge these issues to create positive change. I work from a strengths-based approach and have found that collaboration with clients often yields the best results. While I cannot guarantee an easy journey, I assure clients that they will not be alone on their path to healing.
My areas of expertise include ADHD, trauma, anxiety, depression, PTSD, and addictions. I also have experience working with children, adolescents, and adults. I offer individual therapy, ADHD evaluations, and psychological assessments.

My approach is warm and collaborative. If you’re feeling lost or overwhelmed, I’m here to help you organize your thoughts and emotions, regain confidence in yourself, and achieve lasting change.
In our sessions, I work with you at your own pace to reach your goals, in a space where you feel comfortable, heard, and supported, and where I gently challenge you when needed.
I offer empathy, cultural sensitivity, and respect, and work. best with adults committed to their healing process and personal growth.
