Doctors of Physical Therapy and Snoqualmie Valley Moms, Kaeli Beckham and Shanna Sullivan, are committed to providing deeply impactful, life-changing care: helping people resolve debilitating pain, restore function, and address issues like incontinence that profoundly affect patient's quality of life.

Meet Dr. Greta Tvedt, PT, DPT

Greta earned her Doctorate in Physical Therapy from Boston University. She has a special interest in pelvic floor physical therapy and enjoys working with individuals experiencing a wide range of orthopedic conditions. She uses exercise-focused, evidence-based practices to help clients return stronger and more confident than before, empowering them to take an active role in their recovery.

She finds it especially rewarding to treat sports injuries and, as an avid trail runner, understands the importance of being able to do what you love—no matter your level. Greta is also passionate about supporting women through their pregnancy and postpartum journey. She is committed to helping women feel strong, informed, and confident during life’s many transitions.

Greta grew up in England and finds the weather of the PNW to be a nice reminder of home. She and her husband moved to Washington in 2022 and have fallen in love with the valley. She values giving back to this wonderful community through volunteer work and community education.

Outside the clinic, you’ll find Greta on the trails running or cross-country skiing, or spending quality time at home with her family.

Meet Dr. Kaeli Beckham, PT, DPT

Kaeli Beckham is a Doctor of Physical Therapy and specializes in orthopedic and pelvic physical therapy. She integrates therapeutic exercise, manual therapy techniques, and somatic healing to treat the whole person, not just one body part. As an avid climber, biker, skier, and mountaineer herself, she is passionate about helping mountain athletes recover from injuries and re-discover their body’s capacity!

As someone who has had multiple major orthopedic injuries, she has a compassionate understanding of what it means to feel stuck, alone, and hopeless when injuries keep you from physical pursuits. Kaeli can help you skillfully navigate the whole recovery experience to come out the other side healthy, resilient, and strong.

Kaeli volunteers locally with Seattle Mountain Rescue, a group of seasoned alpinists dedicated to saving lives in the backcountry. She also enjoys sailing, playing ukulele, brewing beer and spending time with her two dogs, family and friends.
