Did not listen to my symptoms. Told me to quit my medicine when clearly that was the wrong advice. I needed to stay on it--and did.

This was my first visit with Dr. Koenig. I can truthfully say that every staff member that I had the pleasure of coming into contact with were very genuinely pleasant and uplifting including Dr. Koenig. I have been scheduled for several procedures to diagnose and treat me, this is what I call caring and compassionate towards my health. The atmosphere made my visit less stressful; I am pleased with my visit.

I was a patient of Dr. Landau for 25+ years. Took 3 weeks to get appointment with Dr. Koenig & the day before the office called to say they had to reschedule for two more days away. When I showed up for the rescheduled appointment, I was told that I was late & the doctor was gone for the day. This looks like a thriving group of 7-8 doctors is now down to 3. Apparently they couldn't stay successful without Dr. Landau's leadership.

The doctor listened to me. He did not just throw me on a medication. He was very patient and he is prompt and know what he is doing. I will post about my progress soon. Thank you! Staff was awesome as well!
