Better Sleep. Lasting Energy

Helping people sleep better, recover more fully, and thrive through evidence-based sleep coaching, CBT-I, movement, and meditation.

Do Any of These Sound Familiar?

  • I fall asleep just fine... but wake up at 3 a.m. and can't get back to sleep.

  • My mind won't shut off when I go to bed.

  • I wake up several times throughout the night.

  • I procrastinate going to bed, even when I'm tired and know I will be exhausted tomorrow.

  • I wake hours before my alarm and can't fall back asleep.

  • I'm tired all day but somehow wide awake when it's finally time for bed.

  • I've tried magnesium, melatonin, CBD, and every sleep hack on Instagram.

  • My sleep tracker has made me more anxious about my sleep.

  • I've become dependent on sleep medication and want another way forward.

    If you nodded "yes" to any of these, you're in the right place.

    Many of these patterns are forms of chronic insomnia and CBT-I (Cognitive Behavioral Therapy for Insomnia) is the gold-standard, evidence-based treatment designed to address them.

What Working Together Looks Like

Sleep coaching isn't about finding the perfect supplement, gadget, or bedtime routine. It's about understanding your sleep. Together, we'll identify the habits, beliefs, lifestyle factors, and health considerations influencing your sleep so we can create a plan that fits your life, not someone else's. Along the way, you'll learn evidence-based strategies rooted in behavioral sleep medicine, rebuild confidence in your body's ability to sleep, and develop lasting habits that support your health, resilience, performance, and well-being for years to come. I also believe the best care is collaborative, and when appropriate, I'll work alongside your healthcare providers to ensure your sleep plan supports your broader health goals

Why CBT-I?

Cognitive Behavioral Therapy for Insomnia (CBT-I) helps people who have difficulty falling asleep, staying asleep, waking too early, or who continue to struggle with insomnia alongside sleep apnea (COMISA). Considered the gold-standard treatment for chronic insomnia, CBT-I is recommended by major medical organizations as the first-line treatment before sleeping medication. Rather than relying on a single technique, we'll combine sleep education with personalized strategies like building healthy sleep pressure, optimizing your sleep schedule, strengthening your brain's association between bed and sleep, reducing sleep-related anxiety, and learning relaxation skills to address the underlying factors keeping insomnia going. You will build lasting, restorative sleep.

What people are saying

  • "Before working with Sarah as my sleep coach I had no idea that lying in bed waiting to fall back asleep was training myself NOT to sleep! Im so glad she cured me of this!"

    Amber

  • “My challenge was to wean myself off of a daily dose of Ambien, which I had been using for years to get to sleep and on which I had become totally dependent. Sarah patiently and expertly worked through the process with me, with great success”

    Bob

  • “I was dealing with some sleep anxiety and Sarah gave me tools to reframe my thoughts. Little by little I became less scared of my sleep, leading to less anxiety and eventually better sleep. She was very attentive to my needs, and I couldn’t recommend her more!’”

    Lucie

  • "Our group really enjoyed the sleep session. A few participants told me they tried the breathing exercise before bed and it worked for them! "

    Tara, HR

  • “Before working with Sarah I had a hard time falling asleep and would wake up early in the morning unable to get back to sleep. I was really struggling with feeling confident in my ability to sleep well and through the night. Working with Sarah on my wind down routine and sleep pressure worked really well for me. My insomnia score went from 10 to 0 in just 6 weeks. Yep, 0. I A good night's sleep is literally priceless and having the support and accountability of a trained sleep coach made the difference that I wasn’t able to make for myself. After coaching, I now feel confident in my ability to fall asleep, and know how to set myself up for success with a good night's sleep.”
