Best Doctor around
April 9, 2026
I am always greeted w a smile fr front desk to nurse to Dr. SIKIC. DR. SIKIC is the best listener, asks valid questions and checks all possibilities. He doesn't just jump to writing a Rx which he knows I am not crazy about meds. He errors on the side of caution and follows up.Endeavor is a very comfortable place of care for me. Im so very grateful for them. [...]
