Treatment approaches

Cognitive Behavioral Therapy (CBT)In cognitive behavioral therapy, you work with a therapist in a structured way, attending a limited number of sessions. Cognitive behavioral therapy helps you become aware of inaccurate or negative thinking, so you can view challenging situations more clearly and respond to them in a more effective way. (learn more)

Mindfulness PracticesMindfulness practices include but are not limited to developing awareness, attention, and remembering.

Self-acceptance and compassion are also core elements of mindfulness-informed therapy. (learn more)
