Support group for fathers specifically

Im an OT working in a critical care access hospital in Iowa. I am curious as to whether or not anyone knows of a virtual support group specifically for fathers? A couple of my lil kiddos who are every bit as vested and active in their childrens care as the mothers; yet feel a sense of not belonging in "regular" autism support groups- as they are all so dominated by women. And then of course being father vs. mother is a different perspective with different emotions involved- different concerns etc... I've done a google search- saw that Drexel has a support group. I'm in Iowa- so contacted the Autism Society of Iowa. There was another site that actually charged to be a member of a group. I have 2 boys with ASD and know how isolating it can be; and dont want these fathers to feel that same isolation.
Any ideas/input would be appreciated. I can most certainly see how the "regular" groups would be more biased towards women. Of course not ALL fathers are rather stand-offish when it comes to their autistic children; but in my experience they are the majority. So women automatically think that fathers dont put in the same amount of emotional/physical energy as the mothers. And of course men are much less likely to reach out for support to begin with.
