Fairfax Allergy, Asthma and Sinus Clinic began more than 20 years ago when Dr. Cheryl C. Rosenblatt completed her
allergy fellowship training at Walter Reid Army Medical Center in Washington, DC.
Dr. Rosenblatt had enjoyed practicing pediatrics for
more than 10 years prior to training at Walter Reid,
but found she had a special ability to help manage
asthma and allergy in her patients. The
practice grew, and soon Dr. Rosenblatt found herself
operating several offices in Maryland, and Virginia.
Dr. Johnson joined Dr.
Rosenblatt in 2001, after serving as the director of
the division of allergy and immunology at Temple
Children's Medical Center in Philadelphia, PA.
The doctors found they had very similar
philosophies, and their focus on treating not just
the disease, but the entire patient, led to happier
and healthier lives for their patients. Since
Dr. Johnson's background was also in pediatrics, he
felt right at home working with infants and young
children, as well as adults.
Dr. Rosenblatt passed away in
2008, but she left us with the charge to carry on
her legacy and continue to treat the patients that
she cared so deeply for. Many of the present
day staff members have been with the practice for
more than 10 years, and have been able to watch
families grow and return with their children.
From all of the staff members at Fairfax Allergy,
Asthma and Sinus Clinic, we wish you a warm welcome
and hope to serve our patients for many years to
