Why I Chose Psychiatry

When it comes to your mental health, you want care that feels practical, thoughtful, and aligned with your priorities.

When care feels rushed or overly clinical, it can be difficult to feel confident about recommendations or clear about next steps.

Many people seek me for psychiatric support because they want more than symptom management. They want clarity, structure, and soemone who communicates clearly and works collaboratively.

My approach is grounded, attentive, and practical. I focus on understanding what is happening in your life and helping you build a clear, steady path forward. – Diana Nguyen

I highly recommend this if you are looking for fast, efficient, and longer visits. My assessment with Charlene went very well. I came away with great clarity and understanding of what I need to do for my school accommodations. She gave me a clear plan going forward. She makes the paperwork very easy, which I appreciate for getting my ADHD accommodations. I have not needed the messaging between visits yet, but it is there and it looks easy to access. I have the app so I can get questions answered. I like that I do not have to call for things. Calling is still an option, but messaging makes it easier because I work long days.

On my first visit I was thoroughly impressed. Within minutes, Jonathan identified a medication that had been causing side effects that I had been on for a long time from my primary care provider. I definitely will not be taking that anymore after I talk to them about it. Great first appointment and an excellent provider. He listens to me and did not dismiss my symptoms at all. He understood quickly what my main symptoms are. What I like is that he helped me prioritize what is most important to address first, and he explained how treating my main symptoms first would benefit the other symptoms. A great way of simplifying it, and I feel genuinely supported.

—Talia

I honestly did not know what I had going on. I just knew it was hard for me to focus. I spent a lot of time doing online research. I wish I had gotten into one of these services previously, but it was hard because I did not have insurance. It is nice that they take a lot of insurances and the billing is easy and not a headache, unlike other places where you have to go through a bunch of hoops to get a real human being. Very easy to reach somebody. I just send a message and Charlene responds within a day. I have not had any bad experiences here. I would definitely recommend it to somebody wanting evaluation and treatment for ADHD or other mental health conditions.
