Dr. Sanjeev Jain, MD PhD 

Dr. Sanjeev Jain was one of the first medical doctors to offer desensitization treatment in private practice, and possibly the first to do combined tree nuts in a single protocol. Educated in allergy and immunology at Yale University, Dr. Jain first received a joint MD and PhD from the University of Wisconsin and finished his residency at the University of Texas. He then taught and practiced at the University of Washington Medical School in Seattle, where he developed a reputation as one of the finest allergists in the region. He has won numerous awards and is included in the Guide to America’s Top Physicians consistently for the last several years.

As an allergist, Dr. Jain treasures the opportunity to witness his patients make dramatic improvements after years of suffering.

He can recall several instances where his patients who had previously required repeated hospital admissions for asthma exacerbations have returned to normal lives free of hospitalizations. In Dr. Jain’s experience, most patients can achieve significant improvements by determining the individual triggers of their allergic reactions and by instituting an appropriate therapy.
