Natasha Amiri
About Natasha
Born and raised on the west coast, I grew up surrounded by the natural beauty of California, spending weekends hiking, camping, and boogie-boarding with my Afghan-French family. After college, I met my wonderful partner, a Colorado native, and we’ve shared 15 amazing years together. Now living in Colorado, we enjoy exploring the Rocky Mountains, hiking, mountain biking, and photographing wildflowers, often accompanied by our beloved hound, Oakley.
My relationship with my partner has shaped my approach to life and therapy. Together, we focus on maintaining respect, adoration, and authenticity—values I bring into my work with couples. I’m passionate about helping others cultivate positive, compassionate interactions in their relationships, fostering understanding and reducing conflict.
My fascination with healthy relationships began early, influenced by role models who embodied compassionate communication and authenticity. This passion led me to study positive psychology, attachment theory, and cultural systems in my academic studies. I’ve always been drawn to the resilience of the human spirit and the power of change.
Growing up in a multicultural household, I learned to value diverse perspectives and the uniqueness of each individual. As a Couple and Family Therapist, I use a systemic, attachment-based, and Emotionally-Focused approach to help clients build stronger emotional connections. I’m dedicated to guiding couples through the process of breaking negative patterns and fostering a deeper, more fulfilling partnership.
