Our focus, as interventional pain specialists, is to provide patients a better quality of life by using injection therapy, along with oral medications, physical therapy and chiropractic care, to help them avoid surgery. 
Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves,  
not looking to your own interests but each of you to the interests of the others. Phil 2:3-4 (NIV)
