Psychiatry for Adults on Oʻahu

Telehealth psychiatric care for adults across Oʻahu — from Honolulu and Kapolei to Kāneʻohe, Mililani, and the North Shore — without building an afternoon around the drive.

Access on Oʻahu is a commute problem, not a distance problem

Oʻahu holds most of Hawaiʻi's population and most of its specialty care. But concentration is not the same as access. Psychiatric appointments cluster in urban Honolulu, which means an hour or more each way on the H-1 or over the Pali for patients in Kapolei, ʻEwa Beach, Waiʻanae, Mililani, Kāneʻohe, or Haleʻiwa. For routine medication management — visits that often run twenty to thirty minutes — the travel regularly costs more than the appointment itself.

Secure-video care removes that arithmetic. You are seen from home, from a parked car on a lunch break, or from anywhere private on the island. Optional in-person visits remain available in Honolulu when a visit genuinely benefits from being face to face.

What we treat

Care includes adult ADHD evaluation, medication management, anxiety and depression, bipolar disorder, and diagnostic clarification and second opinions for adults whose treatment has stalled.

Communities served on Oʻahu

Adults are seen across the island, including Honolulu, Waikīkī, Mānoa, Kaimukī, ʻAiea, Pearl City, Waipahu, Kapolei, ʻEwa Beach, Mililani, Wahiawā, Kāneʻohe, Kailua, Waimānalo, Waiʻanae, and Haleʻiwa. Because care is delivered by video, where you live on Oʻahu does not change what is available to you.

Insurance in Hawaiʻi

The practice is in-network with HMSA PPO and HMSA QUEST Integration and AlohaCare QUEST. Self-pay is available. No referral is required to schedule.

Culturally grounded care

Dr. Casilang is a Filipino-American provider who can conduct evaluations in Tagalog for patients who prefer it — one part of care that takes Hawaiʻi's communities seriously.

Who you will see

You will work directly with Dr. Reginald Casilang, DNP, PMHNP-BC, FNP-BC, a dual board-certified psychiatric and family nurse practitioner, for your evaluation and ongoing care.

Continuity when your schedule is the obstacle

Many adults on Oʻahu do not lack a provider so much as they lack a repeatable appointment. Shift work at the hospitals, hotels, and bases, plus a commute that varies by an hour depending on the direction of traffic, makes a fixed mid-afternoon slot in Honolulu hard to hold for a year. Treatment that depends on that slot tends to lapse — not because it stopped working, but because it stopped fitting.

Video visits are scheduled around that reality, and the record of your care stays with one provider rather than restarting each time a schedule changes.

Frequently asked questions

Do I need to travel into Honolulu to be seen?

No. Adults anywhere on Oʻahu are seen by secure video. In-person visits in Honolulu are available if you prefer them, but they are optional rather than expected.

Do you take HMSA and AlohaCare?

Yes — in-network with HMSA PPO, HMSA QUEST Integration, and AlohaCare QUEST. Self-pay is available.

Can I be seen outside standard business hours?

Scheduling is arranged around your availability where possible, including early and later slots. The specific options are discussed when you request an appointment.

I already see a therapist on Oʻahu. Can you work alongside them?

Yes. Medication management and diagnostic clarification are frequently provided alongside an existing therapist, with coordination when you authorize it.
