    Nothing but good care.
    Jill Olmstead is a caring and wise provider! She listens carefully and patiently.
    Jill Olmstead is the best health care provider I have ever had. She is the only one who has actually followed up with a call to see how I was doing. Everyone at St. Joseph Health should follow her example.
    I am grateful to have been schedule/assigned with Jill. She was very caring and helpful. She listen to all my health concerns and work with me to develop a health plan
    It seems to me that doctors are only interested in the patients & problems/symptoms related to his/her specialty, not the patients overall health and quality of life.
