Why Choose a PhD Therapist?
Doctoral-level therapists have the highest level of training available in the field of mental health. This means they've spent years learning not only how to provide therapy, but also how to understand the science behind what works. Because of this, they’re often on the cutting edge of emerging treatments and deeply understand the "why" behind proven approaches. More importantly, they can adapt these tools to meet you where you are — with care, flexibility, and a focus on what feels right for you.
As a PhD therapist in Denver, Dr. Culnan combines scientific knowledge with a warm, collaborative approach. Her goal is to help you understand the “why” behind your challenges and support you in making sustainable, meaningful changes.
