can you not do a foreach on the

var currentMemberGroups = currentMember.Groups;

foreach (var memGroup in currentMemberGroups)
{
                   do something with memGroup
}

Problem is currentMember is not an IMember. And IMember doesn't expose Groups.

The closest thing I could find to getting groups/roles for a member is using System.Web.Security.Roles.GetRolesForUser

I was going to say unless you are willing to work the wrong way round, ie.

get all the roles and then check if the user is in those roles?? though that feels like a pfaff/dirty workaround..

It is quite dirty indeed. Essentially I need the group Id's the member belongs to.

var memberRoles = System.Web.Security.Roles.GetRolesForUser(member.Username).ToList();
var memberInGroups = new List<int>();
foreach (var role in memberRoles)
{
      var group = MemberGroupService.GetByName(role);
      memberInGroups.Add(group.Id);
}

Seems to work but probably not the way I wanted to write it.

sounds like an API extension issue that needs to be raised.. the list of groups by member

is working on a reply...
