we start with the emergency stuff first, because that always matters more than speed.

Megan received her Doctorate in Physical Therapy at Elon University and has worked in neuro specialty centers in Florida and California. She treats people with complex neurologic conditions, including vestibular dysfunction, stroke, Parkinson's, spinal cord injury, Guillain-Barre, and MS.
Dizzy Decoded is really the kind of resource Megan wishes more people had when they're stuck in that weird in-between of knowing something feels off but not knowing what to do next. Her goal is to make things feel clearer, more grounded, and less overwhelming so people can move toward the right care with more confidence.
Outside of work, she is a dog mom, a soccer player, an occasional salsa dancer, and someone who is always hunting for a good local coffee shop or bookstore. She also hosts The Board Walks, Sacramento chapter.
