Keystone Psychiatry Provider Julius Guiang PMHNP-BC, APRN, MSN

Julius Guiang, PMHNP-BC

Julius Guiang is a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with a diverse and distinguished background in healthcare. He began his medical career as a U.S. Navy Hospital Corpsman, providing emergency medical care to military service members and their families. He later served as a Fleet Marine Force (FMF) Corpsman alongside a U.S. Marine Corps infantry unit, completing specialized military field training and developing the tactical medical expertise required to deliver frontline care in support of infantry operations. This role demanded a unique combination of clinical proficiency, tactical preparedness, and the ability to provide medical care while operating alongside combat personnel.

Following his honorable discharge from the U.S. Navy, Julius earned his Bachelor of Science in Nursing (BSN) from Hawaii Pacific University and went on to spend several years working as an emergency and trauma nurse. Throughout his nursing career, he provided critical care to patients from diverse backgrounds, including veterans, individuals experiencing homelessness, racial and ethnic minorities, older adults, and children. These experiences broadened his understanding of the complex factors that influence health and reinforced his recognition of mental health as an essential, yet often overlooked, component of overall well-being.

Motivated by a strong interest in mental health and a desire to make a meaningful difference in patients’ lives, Julius pursued his Master of Science in Nursing degree at the University of Texas at Tyler, specializing as a Psychiatric-Mental Health Nurse Practitioner. His transition into psychiatric care reflects his commitment to addressing mental health needs through a comprehensive, individualized approach that considers each patient’s unique experiences and circumstances.

Julius believes that mental and physical health are deeply interconnected and that lasting wellness requires attention to both. He is committed to providing compassionate, evidence-based psychiatric care that addresses each patient’s individual needs, supports emotional well-being, and helps improve overall quality of life.

My Approach to Care

I strive to create a calm, collaborative environment where patients feel heard, respected, and supported. Treatment is never one-size-fits-all. I focus on:

  • Comprehensive evaluations

  • Clear, structured treatment plans

  • Thoughtful medication management

  • Ongoing collaboration and follow-up

  • Education that empowers you to understand your care

Whether working with an adolescent navigating academic pressures or an adult managing focus challenges and anxiety, my goal is to provide care that is steady, compassionate, and practical.

Collaborative Care in Texas

Texas has regulations that support collaborative practice between PMHNPs and physicians.

While PMHNPs independently perform psychiatric assessments, diagnose conditions, develop treatment plans, and manage patient care, certain controlled substances require physician delegation and oversight under Texas law. This collaborative approach helps ensure patients receive timely access to treatment while maintaining appropriate physician involvement when required.

Rather than replacing psychiatrists, PMHNPs work as part of the broader mental health care team. Collaboration allows patients to benefit from both advanced nursing expertise and physician oversight where state regulations require it. Our practice maintains an active collaboration with a board-certified psychiatrist (MD), who is licensed to practice in Texas.

Patient-Centered Psychiatric Care

The goal of psychiatric treatment is not simply to prescribe medication. Effective mental health care begins with listening carefully, understanding each person's unique circumstances, performing a thorough evaluation, and developing an individualized treatment plan.

PMHNPs are trained to provide compassionate, evidence-based psychiatric care while building long-term therapeutic relationships with their patients. Whether treatment includes medication, psychotherapy referrals, lifestyle recommendations, or ongoing monitoring, the focus remains on helping patients achieve lasting improvements in their mental health.

Our Philosophy of Care

At Keystone Adult & Adolescent Psychiatry, we believe every patient deserves timely access to compassionate, evidence-based mental health care. Whether your provider is a psychiatrist or a Psychiatric-Mental Health Nurse Practitioner, the most important aspect of treatment is receiving thoughtful, individualized care from a qualified clinician who takes the time to listen, understand your concerns, and develop a treatment plan tailored to your unique needs.

Our goal is never simply to prescribe medication. Instead, we strive to build lasting therapeutic relationships based on trust, open communication, and shared decision-making so that you feel informed, supported, and confident throughout your mental health journey.
