About Us

General Information

We are proud to be the first full-time allergy, asthma, and clinical immunology clinic devoted to the health of McKinney and nearby communities.

For physical address and map, please refer to the Reaching Us section.


Residents of nearby cities (this appears to be most lines in Allen, McKinney, Anna, Melissa, Van Alstyne, Celina, Prosper, Princeton, Farmersville, etc) may call the main local number, 972-540-0777.

A metro calling area number, 972-569-8500, is also available. This number is especially useful for patients who call from other places in the metroplex (such as Plano, Frisco, Richardson, Dallas, etc) from a legacy landline that still has older style long-distance dialing charges.

To call after hours, select the recorded menu option. If this does not go through, try selecting the after hours option when calling in from the metro line.


Due to the lack of a “medical” internet, unfortunately transmission of medical documents still relies on decades-old facsimile technology. For confidential documents, please send to 877-219-5342. An alternate line is 469-519-0551.


Send messages to only if not considered confidential, since email is not considered highly secured. If the materials transmitted by email could possibly include confidential, private health, or financial information, then please use another means of sending the information, in accordance with prevailing privacy regulations.
