Experienced Hawaiʻi clinicians. One connected team.
Counseling and psychiatric care for individuals, couples, families, children and teens, in Honolulu and by telehealth across the islands.
Our story
For ten years, our practice has helped people across Hawaiʻi through some of life’s hardest stretches. What began with deep roots in family therapy and addiction care has grown into a full general practice for counseling and psychiatry, and the name Landmark Counseling reflects that. Family and addiction work remain long-standing strengths, alongside care for anxiety, depression, trauma, relationships and life’s big transitions.
Our team
Our clinicians bring years of Hawaiʻi mental health experience from schools, hospitals, military settings, community programs and private practice. Each has their own focus, so you can find the person who fits you.
