Of course not. One's desire to be successful in search of salvation should be his/her driving force. If a person isn't fulfilled by the teaching at the family church one needs to find a church that will help him/her grow towards God. Consider why the person doesn't want to attend the same church...rationalize the reasons first then address them accordingly. If the reasoning is more attitudinal then the problem is individual not the family or the church. Pray for guidance in the matter.
