After the 1st 45 minute session I noticed some relief immediately. I came to my 2nd session with high level of pain in my hip. After the treatment the pain was greatly improved. After 3 sessions my hips and back feel better than any other treatment. Try it!
I went to Angelika for a session that included her hip release technique, deep tissue massage, and laser therapy. She is very knowledgeable and clearly understands how to work with these kinds of issues. The hip release work felt targeted and professional, and she explained what she was doing throughout the session, which I appreciated.
Angelika is a skilled and attentive massage therapist who takes her work seriously and focuses on the root of the problem. Even though this kind of pain can take time and multiple sessions to fully resolve, I felt like I was in good hands and would recommend her to anyone dealing with lower back pain, sciatica, or hip-related tension.
I thank Katrina and two other therapists at the Rejuvenation office for my speedy recovery even at 72 years of age. I highly recommend this therapy.
