Great class! Really thorough in the training and will definitely be coming back in the future. Mario was my instructor and he was very uplifting and provided a fun but professional environment. Would recommend to anyone in need of the MaskFit or CPR course!!

I had a great experience during my mask fit session. The instructor was very professional, knowledgeable, and explained the entire process clearly. They made sure everyone understood the steps and answered questions patiently. The session was well organized and completed efficiently. I appreciate their friendly approach and attention to safety. Highly recommended.

Patrick Sacco was a great instructor, super friendly and accommodating. Session was thorough and quick (1hr).

I got my mask fit test done and it was excellent service, my instructor was Mario, his class was very fun and informative. I recommend this place since it is quick and easy!
