About Us

A Team-Based Approach to Women’s Health

Thoughtful, evidence-based care guided by experience, collaboration, and respect for how women’s health evolves over time.

Care Built on Experience and Continuity

Plano Wellness is built around a simple belief: women’s health care should be thoughtful, individualized, and supported by ongoing clinical attention.

Our care model brings together physician-led expertise and experienced nurse practitioners working closely as a team. This collaborative approach allows us to provide consistent, high-quality care while ensuring patients receive the appropriate level of attention at every stage of their care journey.

Our Philosophy of Care

At Plano Wellness, care decisions are guided by clinical judgment, medical evidence, and ongoing patient feedback — not trends or shortcuts.

We believe:

This philosophy shapes every visit, every treatment decision, and every follow-up.

Meet Dr. Marlene Diaz, MD

Board-Certified OB/GYN

Dr. Diaz specializes in women’s hormonal health, gynecologic care, and long-term wellness. Her approach focuses on careful evaluation, precise treatment, and ongoing monitoring. She is closely involved in complex gynecologic care, surgical treatment, extended wellness visits, and hormone therapy oversight.

She views hormone therapy as medical treatment — not a trend or a quick fix — and believes it requires experience, ongoing assessment, and individualized adjustment.

Our Nurse Practitioners

The nurse practitioners at Plano Wellness specialize in women’s health and play a central role in patient care. They work closely with Dr. Diaz and follow the same care standards and clinical philosophy.

When more complex issues are identified — including the need for additional evaluation or surgical consultation — care is coordinated directly with Dr. Diaz.

Patients often see nurse practitioners for:
1. Routine well-woman annual visits
2. Ongoing follow-up care
3. Evaluation of symptoms and concerns
4. Care coordination and continuity

A Collaborative Care Model

Care at Plano Wellness is intentionally team-based.

This means:

Patients are supported by a care team that knows their history and works together to guide decisions over time.
