Yes. I know therapists who are divorced and they're good therapists. I would also actually prefer a therapist who got away from a relationship that was no longer healthy or goo for him/her, to a therapist who were staying in unhealthy relationships for the sake of the past. Personally I've never divorced (haven't even married) but I really don't think that a therapist's divorced or other marital status says that much about his/her therapy skills.
