"Do you provide help on how to find home schooling groups for social purpose; faith support; etc. since this is one of the reasons that my husband is somewhat reluctant to homeschool our children?"
Ask the parishes in your area if there are any Catholic homeschool support groups nearby. You may need to ask around a few times as the support groups are not usually formal parish ministries so they may not be listed in the parish office.
St. Thomas Aquinas Academy does have a club called the STAA Inklings that meets monthly online that serves as an informal homeschool "support group" for students in Grades 8 through 12.
It is very important to establish connections in your community, though. Always start with the inquiries at your local parishes and then encourage your teens to participate in STAA's offerings.
