Dear Valued Patient,
For more than 45 years, it has been our privilege to care for generations of women and families in our community. For 30 of those years, we have proudly called Medical City Dallas our professional home.
Today, we are pleased to share an important next step for Carlos and Parnell, MD, PA. Effective Nov. 1, 2026, our practice will join Medical City Healthcare, a part of HCA Healthcare.
Most importantly, your care will continue without interruption. Dr. Monica Diaz, Dr. Wendy Parnell Toles and Dr. Shanica Pompey will continue to care for you at the same location, with the same office hours and contact information.
As part of this transition, we will move to a new electronic medical record system, and you may be asked to complete additional forms at your next visit. Once the transition is complete, your medical records will remain on file with the practice. To access your medical record, contact our office at (972) 566-4862.
This transition is a natural next step in our longstanding relationship with Medical City Dallas and has been thoughtfully and carefully planned. We are excited about this next chapter and the opportunity to continue providing the high-quality, compassionate and personalized care you expect, with additional resources and services available to support you. As we move forward, we remain committed to preserving what has always mattered most – the relationships, personal connections and commitment to excellent women’s healthcare that have defined Carlos and Parnell, MD, PA for more than four decades.
We are deeply grateful for the relationships we have built and the trust you continue to place in us. We look forward to caring for you through every stage of life and building on the legacy of this practice for years to come.
If you have questions or concerns about this transition, please contact our office at (972) 566-4862.
With gratitude and warmest regards,
Dr. Monica Diaz
Dr. Wendy Parnell Toles
Dr. Shanica Pompey
