Allen School’s one-of-a-kind online staffing solution makes a big difference for Dr. Ast With 72% of the population in the United States using the Internet as a resource, it is little surprise that Dr. Frederick Ast, Manhattan allergist/rheumatologist/internist, discovered the Allen School’s Speed Staffing System™ online. What is a surprise, however, is how many Allen School graduates he has hired through the system. Recent Medical Assistant graduates Michelle Castellano, Sandra Mendez, Samantha Rakoff, and Yashminie Singh currently have the privilege of gaining extensive experience under Dr. Ast’s close supervision and caring instruction. Dr. Ast, practicing since 1994, graduated from SUNY Health Science Center (formerly Downstate) in Brooklyn and did his residency at St. Luke’s Roosevelt. He holds a fellowship in Rheumatology at NYU Hospital for Joint Disease and one in Allergy and Immunology at Mount Sinai. He has two offices in Manhattan, one on Park Avenue and one on West 57th Street.
