About Us

Integrative Emergency Services (IES) partners with hospitals to provide the best patient encounter in emergency care.

IES employs an amazing team of experienced physician leaders and advanced practice practitioners (APPs) who deliver uncompromising dedication, providing patients with the best care possible.

IES is led by Dr. Nick Zenarosa, who has a long-standing reputation for providing exceptional Emergency Care Management and Operational Excellence for many clients such as Baylor Health Care System (now Baylor Scott & White Health), John Peter Smith Hospital – Ft. Worth, and others.


IES is dedicated to cultivating best practices in emergency care, providing comprehensive acute care services, creating value, and supporting patients, employees, clients, providers, and physicians in pursuit of the highest quality health care.


  • We don’t just sign contracts with hospitals, we form committed partnerships.
  • We provide a practice environment that allows physicians and APPs to work at the top of their game and elevate everyone around them.
  • We strive to help our providers increase the value of the practice, and we share that value with them.
  • We create a transparent and accountable structure, which allows providers to reach their full potential.
  • We help providers become leaders, both on their shift and within the hospital.
