    How was your appointment with Dr. Willenborg?

    Apr 10, 2019
    I am under the care of Dr. Willenborg for the past 20 years. He is a knowlegeable and caring physician and an excellent diagnostician. He controlled my high cholesterol and my thyroid condition. All his referrals for specialists worked out extremely well. I appreciate his clear explanations of his findings and I feel completely safe and protected from illness under his care. An excellent and a caring physician.
