Natalie Vandenberg

Owner, Registered Provisional Psychologist

“I am deeply humbled by the courage and bravery that my clients show every day in my office.  It is a privilege for me to hear their stories; to hear about their struggles and challenges, as well as their successes and achievements.

I believe that we can all experience growth and positive change within our lives and that we can find clarity of mind and heart.  I believe that we can find ways to live authentically and that we can find our voices and sense of belonging in our worlds.

I have experienced my own struggles with feeling like I was not making the difference I wanted in my life and made the decision to go back to school.  I wanted to find a way to help people in their lives in ways that I found lacking when I needed support.  It is my wish that every experience at Vivid feels supportive, non-judgmental, compassionate and is focused towards finding engagement, balance, and growth.”

Owner of Vivid Psychology and registered provisional psychologist, Natalie has spent over 15 years working within the business sector to help and coach employees within their careers as well as in their daily lives. Natalie has also acted as an advisor to business leaders, providing coaching and mentorship. Natalie has had the opportunity to work with diverse groups of people on a variety of outreach and non-profit initiatives in the communities of Northern and Southern Alberta.

Natalie has a Bachelors of Arts degree in Psychology from the University of Calgary and her Masters of Arts in Counselling Psychology from Yorkville University as well as a Bachelor of Arts degree in Social and Cultural Anthropology from the University of Calgary.

Dr. Anusha Kassan

Registered Pyschologist

“I believe that human connection can be an extremely powerful means of healing and I have a deep respect for people who take a chance and trust the therapeutic process. My love of psychology comes from a longstanding history of supporting the people in my life and I have a natural inclination towards understanding the human condition. I feel extremely privileged that my career path has afforded me the ability to teach and practice psychology as well as conduct research in the area of diversity – Something I am extremely passionate about!

I have a unique orientation to psychology. That is, I believe that the cause of psychological distress lies within our environment and broader society. I also think that everyone has the capacity to make positive changes in their lives. By exploring the aspects of our lives that are not serving us well, we can start to shift how we orient ourselves in the world. In parallel, I believe that adopting a strength-based approach, where we explore what it working well in our lives, can help solidify the changes we are working towards.”

Dr. Anusha Kassan is a second-generation newcomer to Canada who is originally from Montreal. She moved to Calgary with her family five year ago to purse a professorial position at the University of Calgary. She is a registered psychologist in the provinces of Alberta and Quebec.
