At Bowtie Allergy Specialists, we specialize in clinical care for adults and kids with allergies, asthma, eczema, food allergies, and eosinophilic/immunological disorders.  Dr. von Tiehl is double board-certified and is currently accepting new patients.  He is confident, compassionate, practical and professional.  We are located on the South Pasadena/San Marino border (we are the only allergy practice in either city).
