When treatment hasn't worked
the way it should
A diagnostic-first approach — for adults whose treatment history deserves a closer, more careful look.
Insurance accepted · Telehealth across California and Hawaiʻi · Optional in-person visits in Honolulu by request
Dr. Casilang holds a Doctor of Nursing Practice (DNP) — the terminal clinical degree in nursing — and is dual board certified in both psychiatric-mental health and family medicine. This uncommon combination means your evaluation isn't limited to psychiatric symptoms in isolation. It includes a full medical lens, which matters more than most patients realize.
Medical contributors to psychiatric symptoms — thyroid dysfunction, sleep disorders, neurological factors, medication interactions — are reviewed as part of every evaluation. That integrated perspective is what a DNP-level, dually certified provider brings that a single-specialty clinician typically does not.
Dr. Casilang practices telehealth-first across California and Hawaiʻi, and has built The MindCounsel specifically to offer the kind of careful, unhurried evaluation that is difficult to find in high-volume outpatient settings.
What we offer
Each service is structured around careful evaluation — not a faster prescription or a briefer visit.
Diagnostic Clarification
For patients whose diagnosis has never fully fit — or who have received multiple conflicting diagnoses over time. A careful, structured re-evaluation from the beginning.
Second Opinions
For patients who want an independent clinical perspective on their current diagnosis or treatment plan before making a major decision about their care.
Medication Reassessment
For patients whose medications have been adjusted repeatedly without a clear rationale — or who want to understand what they are taking and why.
Complex Cases
For patients with overlapping or difficult-to-treat presentations — where both psychiatric and medical factors need to be evaluated together.
A different pace of psychiatric care.
Designed to be careful, deliberate, and clinically precise — with enough time and attention to actually understand what is happening, and why.
Many patients arrive after months or years of treatment that never fully made sense. Diagnoses that didn't quite fit. Medications adjusted without clear rationale. Partial improvements without a clear understanding of why.
This practice is built around second-opinion level evaluation — a careful diagnostic process, a fresh clinical perspective, and a more deliberate approach to treatment planning.
A different kind of psychiatric care
In psychiatry, diagnostic precision matters. Small differences in interpretation can lead to significantly different treatment paths — some of which are correct, and some of which extend the time a patient spends without adequate relief.
A careful, unhurried evaluation — including a thorough medication history and a structured review of prior diagnoses — leads to more stable, more effective outcomes. It avoids the trial-and-error that comes from treating an incomplete picture.
Dual board certification in psychiatric-mental health and family medicine allows for a fuller picture — one that accounts for the medical contributors to psychiatric symptoms that are often missed when the two are evaluated separately.

Is this the right fit?
This may be a good fit if:
- You've been told you have depression, then bipolar disorder, then anxiety — and none of the treatments have fully landed
- You've tried two or more antidepressants and still don't feel like yourself, with no clear explanation of why
- Your stimulant prescription keeps getting adjusted but your focus, mood, or sleep still feel off
- You want to understand what you're actually taking and why — not just follow a prescription because a prior provider started it
- A medical issue (thyroid, sleep apnea, hormone changes, chronic pain) has never been considered alongside your psychiatric symptoms
- You want an independent second opinion before starting a new medication or making a major change to your care
This may not be the best fit if:
- You're seeking immediate medication changes without a full evaluation
- You need same-day or crisis care — a higher level of care would be more appropriate
- You prefer brief, high-frequency visits over thorough evaluation
Your first visit
The initial evaluation is 60 minutes. We review your history in detail — prior diagnoses, past medications, what has helped and what hasn't. Prior records are welcome and reviewed carefully before any recommendations are made.
Thorough intake
Full psychiatric and medical history, including prior diagnoses and how they were determined.
Records reviewed
Prior records from previous providers are reviewed carefully — they are part of understanding your full picture.
Medication history
Structured review of every medication tried — at what doses, and why it was stopped or changed.
Clear findings
After evaluation, a clear clinical impression with explanation — not just a revised label.

Para sa mga Pasyenteng Pilipino — For Filipino Patients in Hawaiʻi
Dr. Casilang is a Filipino-American psychiatric provider who can speak with patients in Tagalog when English doesn't fully carry the meaning. Many Filipino patients in Hawaiʻi have found that discussing mental health in their first language — and with a provider who understands Filipino family dynamics — changes the depth and clarity of care they receive.
