In-Home BeHavioral PsychoTherapy for Children and Families in Los Angeles

  • ADHD

  • Autism Spectrum Disorder

  • Trauma and anxiety disorders

  • Challenging and disruptive behaviors

  • Children ages 2-12

  • Sibling sets

I am here to help your child grow into the very best person they can be.  I emphasize evidence-based care and behavioral methodologies to quickly reduce challenging behaviors and teach replacement skills to your child. I believe in  a collaborative treatment approach and am happy to work with your child's teachers, or other professionals in your child's life.  When one family member is struggling, the entire family struggles along with them. We'll make a plan to support and address the needs of each person in your family.  I want to support your entire family unit as we make changes together.  


about ME


Therapy is art and science. I use the science of cognitive-behavioral theory and Applied Behavior Analysis (ABA) to provide effective, evidence-based care. I blend the art of listening, connecting and relationship development to provide healing and hope to my clients. 

I am a licensed marriage and family therapist in the state of California. I received my Master's of Science in Counseling, marriage and family therapy from California State University, Long Beach. Before graduate school, I worked as behavior therapist implementing ABA under board certified behavior analysts (BCBA) at some of the best agencies in Los Angeles. After graduating at the top of my class, I interned as a clinical therapist in community mental health centers in East Los Angeles and Orange County while continuing to provide ABA case supervision. My work in community mental health focused on treating trauma, anxiety and depression in children. 

I have over a decade of experience designing, implementing and managing behavioral therapy for children and adolescents.

Individual Therapy for Children (In-Home)

Is your child struggling at home or at school? Perhaps they are facing a difficult issue and you don't have the answer. Maybe you're exhausted from constant arguments, tantrums and melt-downs. Parents come to me when their children are struggling with a wide variety of issues. I treat children from preschool through high school.

Why In-home Therapy?

I come to your home, where your child is most comfortable so I get to know who they truly are. Your child may act very differently in an office setting than they would at home. In the safety of their home, they are more likely to show their true selves and open up about the problem. My aim is to understand how the interactions between your child, their challenges and a complex environment support and reinforce specific behaviors. This allows me to make recommendations individualized to your child in your unique family. 

Family Therapy

Families are complex organisms. I provide family therapy to help the whole family improve or rebuild their functioning. We work together to correct negative patterns, teach new skills and build healthy habits so your family can thrive. 




ParenT Coaching and Support

I love collaborating with parents to support positive behaviors and reduce or eliminate problem behaviors in their children. I believe you are the expert in your child so we design and implement behavior plans together that will work in your home. I teach evidence-based parenting techniques that are effective and foster healthy childhood development. 

Please note: I will not be working with your child individually when providing parenting support.  

Professional consultation

I provide professional consultation to marriage and family therapist, parent coaches, BCBAs and social workers on complex cases requiring expertise in behavioral interventions and mental health disorders. Learn more here
