Getting to know Dr. Daniel Irby
As a board-certified psychiatrist, I focus my practice on medication management for a broad range of mental health conditions. I care about seeing the full picture of who you are — your background, your current struggles, and what you want your life to look like — and I use that understanding to shape a treatment plan alongside you. Psychiatry works best as a partnership, so I make a point of walking you through the thinking behind every recommendation, giving you what you need to make confident choices about your care.
My patients include adolescents, transitional-age youth, and adults. I practice careful, evidence-informed psychopharmacology for concerns such as depression, anxiety, OCD, and related conditions. Getting the medication and dosage right is rarely one-size-fits-all, so I track how you're responding, weigh benefits against side effects, and refine the plan as your situation evolves.
When standard medications haven't brought enough improvement, I also provide interventional treatments. These include TMS (transcranial magnetic stimulation) for depression and OCD, along with esketamine and IV ketamine for treatment-resistant depression. If it seems relevant, I'm happy to talk through whether one of these might strengthen your overall plan.
I earned my MD through the UC Berkeley–UCSF Joint Medical Program and completed psychiatry residency in San Mateo County. My career has been rooted in outpatient psychiatry, with particular depth in psychopharmacology and interventional care, and I keep up with advances in the field so my patients can benefit from current, well-supported approaches. I'm also fluent in Portuguese and speak intermediate Spanish.
Whether you're living with a long-standing condition, wanting a fresh evaluation, or seeking a second opinion on medications you're already taking, you can count on an approach that is thorough, respectful, and centered on your individual needs. I look forward to working with you.
What should a new client know about working with you?
Please note: I do not accept EAP programs.
When we work together, getting to know you as a whole person, not a diagnosis, comes first. Our initial visit is a true conversation: I'll ask about your background, what you're going through right now, the goals that brought you in, and which treatments have or haven't worked for you before. I'd rather hear things in your own words than run through a checklist, because that's how I can design a medication plan around your real life instead of symptoms alone.
My practice centers on medication management, and I take an evidence-informed, collaborative approach to psychopharmacology for conditions such as depression, anxiety, and OCD. You deserve to understand the thinking behind every recommendation, so I'll explain why a particular medication fits your situation, what improvements to watch for, how long it typically takes to work, and which side effects to keep in mind. We make decisions together; I offer the expertise and the options, and you choose what feels right for you.
Thoughtful follow-up is important to me. Because finding the right medication and dose is often a process, I'll keep checking in on how you're responding and fine-tune your plan over time. If standard medications aren't providing enough relief, we can also explore interventional options, including TMS (transcranial magnetic stimulation) for depression and OCD, and esketamine or IV ketamine for treatment-resistant depression.
You can expect me to be thorough, respectful, and never rushed. Your questions are always welcome, and I hope you'll feel comfortable being candid about how you're really doing, including any concerns about medications. I work with adolescents, transitional-age youth, and adults, and I'm fluent in Portuguese with intermediate Spanish.
Whether you're starting treatment for the first time, living with a long-standing condition, or looking for a fresh perspective on your current medications, I look forward to working with you.
What is your typical process for working with clients?
Please note: I do not accept EAP programs.
Our work begins with a comprehensive psychiatric evaluation, usually our longest appointment. I'll explore your current concerns and symptoms, mental health and medical history, medications you've tried and how they affected you, family history, and the goals you hope to reach. I also want to understand your daily life and what matters most to you, because effective treatment should fit the person, not just the diagnosis. From there, I'll share my clinical impressions, we'll review your options, and we'll agree on a starting plan together.
Although my practice centers on medication management, our appointments are never rushed prescription hand-offs. I take time to explain each recommendation: why a specific medication fits, what results to expect, how long it may take to work, and which side effects to watch for. My role is to offer expertise and options; yours is to choose what feels right for you, with my full support either way.
Follow-up visits focus on how you're truly doing, including whether your medication is helping, how well you're tolerating it, and what changes might improve your results. Finding the right medication and dose is often a gradual process, so I monitor closely and make adjustments thoughtfully rather than hastily. Visits are typically more frequent at first and spaced further apart once you feel stable.
If standard medications haven't provided enough relief, I can also explore interventional treatments, including TMS (transcranial magnetic stimulation) for depression and OCD, and esketamine or IV ketamine for treatment-resistant depression. We'll discuss whether these options are appropriate for you and what each involves.
Above all, my approach to care is collaborative, respectful, and unhurried. I welcome your questions and encourage you to be honest about how you're really doing, so we can adjust course together as your needs change over time.
