  • "I have been in chronic pain for at least 10 years. Grateful to have found Dr. Kris she is kind, compassionate and a wealth of information. I am so appreciative for the care provided at Diamond State for the first time I no longer think about my neck or shoulders. Very professional and kind office all the way from front to back!!! I am in the medical field and chiropractic care is definitely under utilized in medicine. My healthcare provider does include chiropractor care so I have won all the way around. I feel fabulous."
