For therapy services I generally meet with clients for 50 minutes on a weekly or biweekly basis, depending on your needs.
Minors are seen on a case-by-case basis.
If you discover that this is not the right fit for you, you will be given referrals to other providers who may be more appropriate for you. I maintain relationships with many psychotherapists, and psychologists for collaboration, consultation, and referral. Finding the right fit is important when looking for a therapist.
