I was a patient of several other Chiropractors due to a mystery spinal and orthostatic intolerance issue. No one could figure out the problem. I was told to seek a "Gentle Activator" method Chiropractor. Dr. Hallgren was one of few in the Las Vegas area who accepted my insurance. Luckily for me he was able to "cure" the intolerance that was preventing me from standing for more than 30 minutes without a trip to the ER in 3 weeks. His methods, care and office staff were second to none. I would HIGHLY recommend his practice for anyone who needs chiropractic care, and DOUBLE recommend "Gentle Activator" method.
