Melissa Leuzzi, NP

Nurse Practitioner

(Reviews Coming Soon)

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.

Melissa brings a compassionate, individualized approach to psychiatric care, offering evidence-based treatment plans that are tailored to each person’s unique experiences and goals. Her focus is on supporting patients through some of life’s most challenging mental health struggles, including depression, anxiety, PTSD, bipolar disorder, and OCD.
