Katrina Herskedal, PT, DPT, CSCS

Katrina enjoyed her undergraduate education at UC Santa Barbara. She obtained a Bachelor of Science degree in biology in 2008.

She then attended the University of Southern California and subsequently obtained her Doctor of Physical Therapy degree in 2011.

Katrina is also a Certified Strength and Conditioning Specialist (CSCS) and a member of the NSCA.

She enjoys working with patients that are active in recreational sports including both high school athletes and weekend warriors. Her advanced training has enabled her to successfully care for just about any patient with a movement disorder. She does specialize in the treatment of extremities - shoulders, knees, and ankles.

Her philosophy is to treat not on the pain but the underlying problems (abnormal movement) causing the pain. She accomplishes this through extensive patient education, highly skilled hands-on therapy techniques, functional and core training, and pain-relieving treatments such as heat, ice, ultrasound and electrotherapy.

Katrina is very active in her spare time. She enjoys:

• Cycling
• Hiking
• Volleyball
• Spending time at the beach.
