Hi, I’m Allan. I’m a board-certified psychiatric mental health nurse practitioner, and I’ve been a nurse for over 20 years.
If you’re here on my website, you may be dealing with anxiety that won’t let up, you may be having trouble sleeping, your mood may be off, people may be saying, “Hey, is there something wrong?” That’s okay. You don’t have to have it figured out before you get ahold of me. We can figure it out together.
We won’t rush through anything. We’ll just talk. We’ll go through your history and what’s going on right now. I’ll explain what I see, what I think may be happening, and we’ll talk about the options and figure out a plan together.
Sometimes that plan includes medications. Most often it includes looking at your life as a whole: your sleep, your work, working with your therapist, maybe your nutrition and your exercise. And we figure out ways to make your life better.
I’d be happy to meet with you and see if we’re a good fit.
