Dr. Reginald Casilang

I work with adults who have already been in treatment, but still feel that their diagnosis or care plan never fully made sense.

Some have tried multiple medications with only partial improvement. Others have received different diagnoses over time without clear explanation. Many are left feeling uncertain about what is actually driving their symptoms.

My practice is built around a more structured, diagnostic-first approach. I focus on clarifying the clinical picture before making treatment changes, so that recommendations are thoughtful, targeted, and easier to follow and make sense of.

This is often a good fit for patients seeking:

• second-opinion evaluations

• diagnostic clarification

• medication reassessment

• a more careful and individualized approach to care

I provide telehealth care for adults across California and Hawaiʻi.

My approach is grounded in careful listening and a structured psychiatric assessment.

I focus on understanding how symptoms affect attention, mood, sleep, energy, and daily functioning — not just how they appear on a checklist. When prior treatment hasn’t fully worked, we slow down and look more closely at the underlying clinical picture.

This often involves revisiting the diagnosis, identifying overlapping conditions, and refining treatment strategy to be more precise and sustainable.

Medication management, when indicated, is deliberate and evidence-based. The goal is not rapid changes, but steady, meaningful improvement supported by clear clinical reasoning.

My focus is diagnostic clarity, treatment precision, and long-term functional progress.

The first session is comprehensive and structured.

We will review your history in detail, including prior diagnoses, medications, therapy experiences, medical conditions, sleep patterns, and current concerns.

You can expect:

• Thorough diagnostic assessment

• Clear explanation of clinical reasoning

• A collaborative and individualized treatment plan

• Thoughtful, structured follow-up

If you are seeking a second opinion or a more thorough reassessment of your care, you will find that the pace is intentional and the clinical reasoning is clear.
