Congratulations to our own Dr. Nathan Alan Harris for recently being named as one of two allergists in Castle Connolly’s Top Doctors List for the Allergy & Immunology specialty!  Doctors are nominated by their peers as best in their region in their medical specialty.  

Congratulations Dr. Harris!



For a few days in May until 3 pm, an elevator repair job is expected to produce very loud, prolonged noises. (The dates keeps changing.) We will work toward toward the back of the office or reschedule visits if  the noise is too disruptive.  We apologize for this inconvenience. Injection patients may call ahead to check status of this job if you wish to avoid the noise, or come in after 3 pm.
