With over 30 years of experience, I help adults manage sleep, stress, anxiety, depression, and ADHD. People often describe me as kind, perceptive, with a good sense of humor. My approach combines active listening, mindfulness, CBT, and applied neuroscience. We'll work together to create a plan tailored to your needs to help you focus and move forward with confidence. I'm an LCPC, Board Certified in Neurofeedback, with a certificate in CBT-I for insomnia and other sleep concerns.
