Jehovahs Witness question

As a parent would you be comfortable sending your young child to a dance studio (ballet/tap) that is run by a JW family?

We’ve attended for a couple of years now. The first year we didn’t know that they were JW until the very end of the season, when I heard some of the parents talking. Several of the parents/families that attend are also JW. The studio owners are nice, maybe a bit odd at times but very nice. I just don’t know how much they normally proselytize? My kiddo is very impressionable. I grew up in a slightly cultish setting myself, so maybe I’m a bit sensitive to the situation?

Anyways, would this concern you at all? My kiddo live dance and any other studio is 30+ minutes away.
