Having someone with empathy and so much passion as your dive guide is very rare. She made us feel like family as opposed to just being cattle.

Shaharil A.

Becoming a mermaid and having someone make you feel beautiful and majestic is an experience like none other!

Jenny T.

This is the best hands down cert I’ve ever taken. I needed an EO2 certification and found Ruth & Larry who offered the DAN version!


It was much harder than I anticipated, and I was very overwhelmed and frustrated with myself, but Lisa was very patient and helped me get through it.

Vicki C.

Lisa was the ultimate professional, patient, credible and people person. This course wouldn’t have been successful without her people/ psychology of learning skills.

Mike R.

Lisa was great! We had a small group with different ages and experience levels, and she gave individual attention based on all our specific needs.
