Endurance can help.

Endurance Behavioral Health is New Hampshire's original mental health partial-hospitalization program (PHP) and intensive outpatient program (IOP) for adolescents ages 13-20, available both in-person and online.

Why choose Endurance?

Is your teen or emerging adult struggling with:

  • Experiencing significant mental health concerns
  • Struggling to attend or engage in school
  • Looking to avoid future hospitalization
  • Temporarily requiring more support than outpatient therapy can provide

“…then, just when things looked their worst, they changed for the best. I have marveled often at the thin line that divides success from failure and the sudden turn that leads from apparently certain disaster to comparative safety.”
– Sir Ernest Shackleton

We collaborate with caregivers, clinicians, schools, and other members of the adolescent’s team to best support their recovery.
