Leaders In Child Psychology

For over twenty-five years, Rocky Mountain Psychological Services (RMPS) has developed a reputation as a leader in pediatric psychology services in the Calgary area. Our team of experienced psychologists and clinicians is dedicated to helping children and teens work through emotional, behavioral, and developmental challenges, supporting their growth into confident and successful young adults.

We understand that the childhood years can be difficult to navigate – we’re here to help! Did you know that working with children is a specialty and requires specific training? Children aren’t little adults and that’s why each of our staff completes specialized training for working with children and has expanded skills for evaluating a child’s development, behaviour, and factors that might be contributing to the reason for referral. Your child and family deserves to have an individualized plan that is grounded in research and tailored to each child’s unique needs. We’re here to help and offer child psychology services in the Calgary area (and beyond!) to address a wide range of concerns, including anxiety, ADHD, learning difficulties, and more.

We also recognize the vital role that parents and families play in working with children and families. Our services naturally extend to working with adults; we offer parenting support and counselling as well as comprehensive assessments for conditions such as ADHD, learning disabilities, and Autism. Additionally, we also offer services for youth transitioning to adulthood who may need assessments for post-secondary, AISH and PDD, as well as capacity assessments.

Our goal is to offer one-stop, wrap-around and specialized services for children and families in Calgary. We look forward to serving you and helping you and your child to take the next steps towards improved functioning in school, life, self-awareness, and in relationships. We offer both in-person sessions at our downtown Calgary clinic and secure telepsychology services available across Alberta, ensuring accessible, compassionate care for all who need it.

Our Services

Comprehensive Psychology Services

Your One-Stop Center for Complete Psychological Support

From Children to teens, and their families, we offer a full spectrum of clinical services designed to meet your unique needs. Whether it’s emotional, behavioral, developmental, or relational challenges, we’re here to help.

Children

We offer age-appropriate services (counseling, assessment, and alternative therapies like neurofeedback) to help children reach their potential cognitively, mentally, emotionally, and relationally. We help children to improve their functioning at home, school, and the places in between.

Teens

We offer age-appropriate services to ensure that a teen has the foundation they need (cognitively, mentally, emotionally and relationally) to reach their personal goals whether that is through counseling, formal assessment, family counseling, or alternative therapies like neurofeedback.

Adults

We help adults, caregivers, and parents improve communication, reduce stress, and develop tools for healthy family life. That can mean working directly with adults or parents, involving parents in their child’s therapy, or it could look like individual counseling for the adult/parent.

Expressive interventions in art therapy can treat behavioural issues, anxiety, depression, ADHD, autism, learning disabilities, physical and developmental disabilities, and attachment difficulties.
