Dr. Nathaniel Brooks, MD

Psychiatrist

About Andrew Nichols, NP

Andrew Nichols, NP has over 10 years of healthcare experience spanning both military and civilian nursing. Born and raised in Houston, Texas, Andrew brings a sense of community to everything he does, and that same grounded, personal care carries into every patient interaction at Serenity.

Education and Background

Andrew earned his advanced practice degree from Texas State University and pursued specialized training in psychiatric mental health care. He served as a Lieutenant in the U.S. Navy, working as a Critical Care and En Route Care Nurse at Naval Hospital Okinawa and with the 3d Medical Battalion.
He joined Serenity drawn by the practice’s commitment to interventional treatments, including TMS and ketamine therapy, that go beyond conventional options to offer patients real, evidence-based paths forward.

Care Philosophy

Andrew approaches each session by staying present and grounded during even the most difficult moments. He meets every patient with understanding rather than judgment, and with care that is guided by clarity, honesty, and a genuine belief that treatment works best as a collaborative process.

What to Expect

In your first visit, Andrew will take time to understand what has been going on and what matters most to you before anything else. From there, you will build a plan together, one that feels manageable and effective. He listens closely and makes sure nothing important gets missed.

Personal Interests

When Andrew is not with patients, you will likely find him at the gym, reading a book, or practicing mindfulness. His greatest joy, though, is time with his kids, including volunteering at their school where he leads science experiments and happily takes on lunchtime duty.

About Dr. Nathaniel Brooks, MD

My Care Philosophy

I firmly believe in non-judgmental and compassionate care. Every patient is different and should have access to individualized care that addresses their needs and concerns while treating with the highest level of evidence-based treatments. I also believe overall nutrition and physical health, are integral parts of improving mental health and well-being.

Why I Chose Mental Health

I was drawn to psychiatry because I enjoy connecting with my patients. Understanding a person’s background and experiences plays a significant role in their treatment and response, and psychiatry gives me the opportunity to look at more than just a physical exam or lab test and use the overall human experience as the basis for treatment. I’m excited to be a part of a clinic that prioritizes the best mental health experience for every patient, from staff that truly cares to the most effective mental health treatments available.

Interests & Activities

I have a wife, two young children (with plans for more), and our dog who’s been with us since college. I recently set a goal to become fluent in Spanish, and in my free time, I enjoy volunteering, sports, and outdoor activities.
