Where do most of your referrals come from?

I can speak to the SF community on this.  We accept referrals from all 21 community outpatient clinics in the SF Dept of Public Health Network.  However, just over half of our referrals come from within the ZSFG hospital services (Peds primary care, Urgent Care, Emergency Room, and inpatient wards), and are primarily asthma rather than allergy referrals. 

Our referrals come from clinic and community partners. We have a web-based referral sheet that anyone can fax into us at
