Dr. W. Carroll epitomizes UCLA's goal to ensure all its pts feel comfortable & safe; listened & heard; valued & respected! His passion for helping us, motivated by I believe, a desire to make a positive impact on pts lives. He is sensitive to & respectful of my values & concerns & preferences, promoting a pt centered care wherein I feel positive & empowered to be an active participant in my own health care. Today, we evaluated existing care plan, gained new diagnostic & surveillance information then planned next steps for 2 active problems including, communications with other specialists involved in my care. This is patient care at its best!
