Katherine Petty PhD

Post Doctoral Intern

I find true joy, inspiration, and hope from connecting with children and their families. I am passionate about mental health, compassion, and empathy. I became interested in helping children and families during my work in schools, where I supported children who were struggling to learn to read. In so doing, I found that I wanted to know more about the psychological aspects of education, ways to nurture mental health, and ways to foster positive family interactions. The wonderful training and experiences I’ve had since my first time in a classroom have allowed me to engage with children and families in schools, homes, clinics, and in the community. Learning about, listening to, and working with people to implement effective strategies is what I love to do, and I look forward to continuing to support families. I have been fortunate to work as a mental health professional in a variety of settings and I am excited to learn about people, be a catalyst for positive changes, and be a dedicated member of each family’s team.

I have worked with young people experiencing challenges related to:

  • Attention-Deficit/Hyperactivity Disorder (ADHD)
  • Learning and academic struggles
  • Behavioral difficulties
  • Anxiety and Depression
  • Thoughts of suicide
  • Social and family stress
  • Autism Spectrum Disorder (ASD)



I have more than 9 years of experience working with children, families, and school professionals in both school and clinical settings.
