Co-parenting Counselor Recommendations Needed

Hi, I'm seeking recommendations for a tried and trusted co-parenting counselor, a male counselor in particular. My husband of 15 years and I are separating, we have a 5 year old child. We need someone to guide us through custody decisions with our daughter's best interest at-heart. My husband is distrustful of therapists and would feel more comfortable working with a man. Hoping for a down-to-earth, honest, sensitive and fair person to fill this role. 

We can travel as far north as Richmond, as far south as Oakland (we are in East Bay).

Thank you!
