Angela Oakley, PMHNP

Psychiatric Mental Health Nurse Practitioner

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 Angela Oakley, PMHNP

Angela Oakley, PMHNP, brings a deep commitment to holistic mental health care at Serenity Mental Health Centers in Phoenix, AZ. With a diverse background in intensive care, emergency medicine, and family practice, Angela has over a decade of experience helping patients navigate both physical and mental health challenges. This foundation gave her an integrated view of the mind-body connection, which she deepened through her recent post-master’s certification as a Psychiatric Mental Health Nurse Practitioner. Angela is passionate about supporting patients in every dimension—mental, emotional, physical, and spiritual—to help them become the best versions of themselves.

Angela’s approach is one of thorough, compassionate care. Known for her commitment to learning and evidence-based practices, she believes in collaborating with patients and other healthcare providers to ensure well-rounded, effective treatment. Angela’s patients can expect her full attention, knowing she values their journey and works tirelessly to address their unique needs. Her time as a family nurse practitioner taught her the importance of integrated care, where each patient’s overall wellness is supported by a collaborative healthcare team. Angela’s experience in family medicine means she understands the value of connection and continuity in mental health, especially for patients who may be new to psychiatric care or have complex needs.

Outside of her work, Angela finds balance through family time, nature, and physical activity. Her daughters are her pride and joy, with two horses that keep the family busy with equestrian show jumping. Her three dogs are also beloved members of the family, with one already serving as a therapy dog in her ketamine clinic and another in training. Angela’s love for yoga, the ocean, and the outdoors helps her recharge and stay centered.

Angela’s compassionate care is grounded in her commitment to being her best self for her patients and loved ones. She strives for peace at the end of each day, dedicated to delivering care with kindness, patience, and understanding. Angela looks forward to providing Phoenix residents with comprehensive mental health support, including ketamine therapy, TMS, and a patient-centered approach that makes every individual feel heard and valued.
