yes it is (was) a place that sold medical-grade oxygen supplies (cpap, asv, bipap and etc) and performed evaluations. however, it appears they closed it? not sure. the website hometownoxygen.com redirects to promptcare.net (is it supposed to be promptcare.com? not sure, and archive.org shows that change happened in 2021 sometime. either way, at the exact location shown on this marker, this has been a pediatric dentist for as long as i can remember, maybe the oxygen place was inside peace medical center? i don't remember seeing a sign for it when i used to deliver here.
