  • Proffesional caring service provided
    Excellent health care service. The staff is always polite.
    Always impressed and protected by Dr. Johnston and his staff.
    Dr. Johnston was courteous and made me feel at ease. The office staff were all courteous and efficient. The young lady who did the check out process and scheduled my tests was extremely efficient, knowledgeable, and very nice, not only to me but other patients.
    This provider is my Cardiologist and I saw him for a routine annual visit.
