Patients Seen: All Ages

I have more than two decades of expe­ri­ence treat­ing patients of every imag­in­able back­ground, with dig­ni­ty, respect, dili­gence, and kind­ness. I have the joy of hav­ing six delight­ful kids, who proud­ly include Asian, African-Amer­i­can, and Cau­casian ances­try, mem­ber­ship in the LBGTQIA+ com­mu­ni­ty, and in the spe­cial-needs com­mu­ni­ty. I am an enthu­si­as­tic, hum­ble learn­er about these com­mu­ni­ties and others.

One of the joys of my spe­cial­ty is that we treat patients, from infants to seniors, for a con­tin­u­al­ly chal­leng­ing vari­ety of con­di­tions. I am an Iron­man triath­lete and I espe­cial­ly enjoy treat­ing ath­letes who are deal­ing with exer­cise-relat­ed res­pi­ra­to­ry and aller­gic conditions.
