About
At Change by Doing Coaching, I help clients create meaningful, lasting change through a collaborative, practical approach to hypnosis and coaching. I am a certified hypnotherapist trained through Paul McKenna/Mindvalley and the Mike Mandel Hypnosis Academy, with specialist training through the American Hypnosis Association.
My practice focuses on helping clients move beyond test anxiety, insomnia and sleep disorders, and trauma-related challenges, including PTSD, CPTSD, and moral injury—particularly among first responders.
Every session is tailored to the individual. Rather than relying on one-size-fits-all scripts, I use a conversational, collaborative style that combines hypnosis with coaching and evidence-informed psychological strategies. Together, we work to quiet the noise, strengthen resilience, improve sleep, build confidence, and help you perform at your best when it matters most.
