  • I have been seeing Dr. Steffan for 20+ years. He told me he was retiring in July, I hate to see him go. I'm sure there is another Doctor that will take excellant care of me like Dr. Steffan.
    I always receive an excellent service, everyone in the office is very friendly and courteous. I will highly recommend Dr. Steffan to others.
    best of the best!!!!!
    Dr. was very nice and said very little. Was not able to diagnose my problem, but was prescribed meds.
    I can't say enough positive about Dr. Stephan. He doesn't seem rushed, spends time to make inquiries about health and has a great wit. I feel very fortunate to have Dr. Stephan as my PCP.
