    Confident in care provider excellent.
    Perhaps best experience in recent years!
    Dr. Ackeroyd is very personable and intelligent, providing a relationship that makes me comfortable and confident.
    I am 80 years old and have numerous health care providers. Greg is the best of the lot! He never tries to contain the visit to 5 or 10 minutes like my other specialists--he gives me the amount of time I need and shows a genuine interest and concern in my issues. I feel like he is there for me, and I don't have to worry.
    Good experience. Doctor is very knowledgeable and respectful -
