Training & Experience 

  • B.S. in Psychology with a minor in Education from Whitman College
  • Ph.D. in Clinical Psychology from the University of Oregon
  • Clinical Internship at University of New Mexico Health Sciences Center
  • Residency at Behavioral Diagnostics & Treatment

I graduated with my Ph.D. in Clinical Psychology from the University of Oregon in 2018. My clinical experiences focused on assessment and therapy for children, adolescents, and young adults from diverse backgrounds and with complex histories and symptoms. My clinical experiences have included assessment and treatment of children, adolescents, and young adults with significant emotional and behavioral challenges due to depression, anxiety, ADHD, Autism Spectrum Disorder, PTSD, or other environmental factors. I received specialized training and experience assessing and treating children and adolescents with challenging behaviors due to disruptions in their caregiving environment such as a history of foster care or adoption.  My assessment experience includes conducting comprehensive assessments to identify the root of why children may be having a hard time at home, school, and/or in their social environments.

Current Practice

I am a licensed psychologist practicing at Behavioral Diagnostics & Treatment. My clinical work emphasizes extensively researched and evidenced-based methods shown to meet clients’ needs.

My clinical work is strongly influenced by motivational interviewing, social learning theory, behavioral and cognitive-behavioral approaches, and trauma informed care. I view assessment and therapy as collaborative processes in which we will work together as partners to fully understand you or your child’s strengths and weaknesses, provide effective and efficient treatment to help you meet your goals, overcome barriers, and live the life you want yourself or your child to be living.

Therapy Services

Many families are feeling intense pressure to meet more demands and achieve at higher levels than ever before. Parents often find themselves frazzled, with less time and energy to maintain consistent family routines or spend quality, technology-free time with their children. Managing this family stress shouldn’t have to be a full time job. Creating a cooperative communication style with young children helps parents form strong bonds and helps them smoothly manage busy schedules with less stress. Behavioral therapy helps parents and children become an effective team.

I work with families who would like to:

  • Increase cooperative interactions with their children
  • Decrease their children’s challenging behaviors
  • Prevent disruptive patterns of behavior from developing
  • Decrease household anxiety
  • Set and maintain boundaries with screen time and electronics
  • Identify and build on their current parenting strengths
  • Improve family problem solving with each new challenge

When providing therapy for children, I view parental involvement as crucial to children’s therapeutic success for several reasons. First, parents provide important information about their children’s past and present experiences which helps me identify specific therapy goals and determine targeted interventions. Second, parent involvement is vital to help parents fully understand their children’s emotional experiences and behaviors. Third, it is difficult for anyone, especially children, to generalize skills learned inside the therapy room to their natural environments; including parents in the therapeutic process allows parents to help their children practice and generalize skills to reduce depressive or anxiety symptoms.

Assessment Services:

I provide early childhood assessments for children aged 4-10, including assessment of behavioral, social-emotional, and family functioning.
