It’s okay to need support. Life can become overwhelming when anxiety, mood changes, trauma, depression, or panic begin affecting your ability to feel like yourself. You may notice your mind won’t slow down, your sleep is off, or it’s harder to focus and keep up with daily responsibilities. When stress builds or world events add to the weight you’re carrying, it can start to feel like too much to manage alone. Many people reach a point where coping strategies no longer feel like enough, and that’s often when support can make a real difference.
I believe care should feel personal, not rushed or one-size-fits-all. I take time to understand your story, not just your symptoms, and create a space where you feel comfortable being open without fear of judgment. I’ll be honest and supportive, helping you make sense of what you’re experiencing while offering guidance that feels practical and manageable.
My goal is to help you feel more balanced, clear, and confident in navigating your day-to-day life.

Headway makes it easy to find support for your mental health — from finding the right provider, to understanding costs, to scheduling with ease.
Finding psychiatrists in Tyler starts with knowing what type of mental health care you need. Psychiatrists and psychiatric mental health nurse practitioners can diagnose conditions, prescribe medication, and manage medication over time. Therapists provide talk therapy and support with different goals. If you are looking for care related to anxiety, depression, ADHD, bipolar disorder, or obsessive-compulsive disorder, a psychiatrist may be part of your care. Review each psychiatrist’s listed specialties, training, and approach so you can compare options based on your needs.
In a smaller city like Tyler, local appointment options may be more limited than in larger Texas metros, so virtual psychiatry can expand the number of psychiatrists available to you. Consider practical details like appointment times, whether the psychiatrist is accepting new patients, session format, and whether their profile mentions medication management, therapy, or both. Psychiatric appointments for medication management are often shorter and less frequent than therapy sessions. Some psychiatrists also offer therapy, and some people work with both a therapist and a prescriber.
Psychiatric care in Tyler can be a significant expense without insurance. Using in-network insurance is one of the most reliable ways to reduce session costs and see your estimated cost before you book. Headway helps you search for psychiatrists who match your preferences, accept your plan, and are verified as accepting new patients. You can review bios, compare availability, and book directly when you’re ready.
If you're already taking psychiatric medication and considering switching providers, talk to your current prescriber before changing or stopping any medication — most psychiatric medications shouldn't be stopped abruptly. Anyone experiencing thoughts of self-harm or in acute crisis should call 988 or go to the nearest emergency department rather than wait for an outpatient appointment.
