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: EAP programs are not accepted.
My first priority is getting to know you as a whole person, not simply a diagnosis. Our initial visit is a real conversation. I'll ask about your background, what you're experiencing right now, the goals you'd like to reach, and which treatments have or haven't worked for you before. Rather than running through a checklist, I'd like to hear your story in your own words, which helps me create a medication plan that fits your daily life, not just your symptoms.
My practice is dedicated to medication management, and I use a collaborative, evidence-informed approach to psychopharmacology for conditions such as depression, anxiety, and OCD. You deserve to understand the reasoning behind every recommendation, so I'll explain why a particular medication fits your situation, what improvements to watch for, how long it usually takes to work, and which side effects to keep in mind. Decisions are made together: I offer expertise and options, and you decide what feels right for you.
Consistent follow-up is important to me. Finding the right medication and dose is often a process, so I'll keep checking in on how you're doing and fine-tune your plan as needed. If standard medications aren't providing enough relief, we can also explore interventional treatments, 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. Questions are always welcome, and I encourage you to be open about how you're feeling, including any concerns about medications. I work with adolescents, transitional-age youth, and adults, and I'm fluent in Portuguese and speak Spanish at an intermediate level.
Whether you're starting treatment for the first time, living with a long-term condition, or looking for a fresh perspective on your current medications, I look forward to working with you and helping you feel better
What is your typical process for working with clients?
Please note that I do not accept EAP benefits. Our work starts with a thorough psychiatric evaluation, usually our longest visit. I'll ask about the concerns and symptoms you're currently experiencing, your mental health and medical history, medications you've tried and how they worked for you, family mental health history, and the goals you hope to reach. I also want to learn about your daily life and what matters most to you, because effective treatment should fit the person, not just the diagnosis. Afterward, I'll share my impressions, and we'll review your options and agree on a starting plan together.
My practice centers on medication management, but our appointments are never rushed prescription visits. I take time to explain each recommendation, including why a particular medication may be right for you, what results are realistic, how long it may take to work, and which side effects to watch for. I offer expertise and options; you choose what feels right, with my full support either way.
Follow-up visits focus on how you're truly doing, including whether your medication is helping, how your body is tolerating it, and what adjustments might lead to better results. Finding the right medication and dose often takes time, so I monitor your progress closely and make changes thoughtfully, never hastily. Visits are typically more frequent at first and spread further apart once you're stable.
If standard medications haven't provided enough relief, I can also talk with you about interventional treatments, such as TMS (transcranial magnetic stimulation) for depression and OCD, and esketamine or IV ketamine for treatment-resistant depression. We'll explore whether any of these may be a good fit and what each involves.
Above all, my approach is collaborative, respectful, and unhurried. Your questions are always welcome, and I encourage you to tell me honestly how things are going, so we can adjust course together as your needs change.
