From my experience I’ve learned that carefully listening to a client and asking them questions ensures a successful therapeutic session. Employing many techniques such as Swedish, deep tissue, trigger point, stretching, and myofacial will relieve pain, stiffness, tenseness, or overused muscles or just help you unwind.

In my spare time I enjoy reading, theatre, ballet and concerts.
