My Services

ADHD Evaluation and Diagnosis

I provide comprehensive ADHD evaluations that consider your child’s developmental history, current difficulties, and functioning across settings. Evaluations include interviews, standardized assessment measures, behavioral observations, and information from parents, teachers, and other relevant professionals.

Autism Spectrum Disorder (ASD)

Whether you’re an adult diagnosed with ASD or a parent wondering about your child, you may be trying to find a clear path forward. ASD presents differently in each person, so I first try to understand the person and their situation before making recommendations.

Co-parenting, Divorce, and Blended Families

Divorce, co-parenting and blending families each bring a host of difficulties. You may be finding it hard to agree on what’s best for your child, figure out how to protect them when conflict arises, or respond to the effects of family changes.

Dr. Marissa Gran, family therapist in San Diego, CA

Meet Dr. Gran

I’m a licensed clinical psychologist with more than 16 years of experience working with children, adults, and families in county mental health, schools, and private practice. My experience includes supporting individuals with anxiety, depression, ADHD, stress, relationship concerns, and autism spectrum disorder.

​

I’m a Certified Autism Specialist and a certified Parent-Child Interaction Therapy (PCIT) provider, with training in Parent Management Training. I work with parents on concerns such as defiance, aggression, emotional regulation, parenting, and co-parenting challenges.


My training and experience allow me to tailor therapy to each person’s needs, strengths, circumstances, and goals. I draw from humanistic and behavioral therapies and collaborate with clients and families to develop practical skills, strengthen relationships, and support positive change at home and beyond.
