About Asthma & Allergy Clinic

The Columbia Asthma & Allergy Clinic is a state-of-the-art facility that provides comprehensive evaluation and treatment for adult and pediatric patients suffering from allergy related illnesses such as asthma, hay fever, and hives. The clinic provides a full ranger of services, including all forms of allergy testing, medical care, immunotherapy (allergy shots), and consultation regarding environmental control measures to help alleviate allergy symptoms. The clinic also stocks an array of allergy control products and supplies, as well as medical equipment such as nebulizers for the treatment of asthma. In addition to regular outpatient therapy, the clinic has an extended stay facility where patients can undergo testing or treatment that requires several hours to complete. Examples of such services include medication desensitization, “rush” immunotherapy, and placebo-controlled food challenges. The Asthma & Allergy Clinic also has its own in-house lab facility for in-vitro allergy testing, which distinguishes it from other clinics in the area. Having his own lab allows Dr. Jain to receive results and prescribe treatments to patients much more quickly. The facility also provides clinical lab services for patients receiving medical care elsewhere. The lab offers free specimen pickup and twenty four hour turnaround time for laboratory results.

Dr. Sanjeev Jain, MD, PhD
Medical Director

Dr. Sanjeev Jain, MD, PhD, started the Asthma & Allergy Clinics in November 2005 to provide the highest quality allergy and asthma care in the comfortable environment of a friendly community facility.

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 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.
