12 Wednesday, August 19, 2020 The Nugget Newspaper, Sisters, Oregon Hummel offers laser therapy Correspondent Last summer Sisters Elementary School nurse Beth Hummel took a leap of faith and bought a class IV heat laser, a powerful thera- peutic instrument that uses focused light to stimulate a process called photobiomod- ulation (PBM). It marked the launch of her new business, Hummel Massage and Laser Therapy. With 23 years in nursing and 15 years as a massage therapist, Hummel was eager to begin a new chapter using the healing light source that changed her life, moving her on the road to recovery from chronic back pain.
