How likely are you to recommend Dr. Thiel?
Love Dr Thiel! He is old and wise and full of knowledge. After coughing from October-February for 10 years, no one could figure out why....untill Dr Thiel! He has been a life saver as I had mold, dust, ragweed and several other allergies I was unaware of. After just 8 weeks of shots, I am cured of the cough! Its been over a year and now I take shots every other week. Thank you Dr Thiel :)
