Meet the Team

Thompson Peak Internal Medicine works hard to constantly improve the care provided to its patients. We focus on engaging patients in a supportive, meaningful, team-based approach. This allows us to keep our patients healthy by supporting their wellness goals and allows us to better manage acute and chronic illnesses. In order for us to provide the most convenient and supportive care possible, our care team includes you, your physician, nurse practitioner, medical assistants, and administrative professionals.  


Physicians lead your care team.  They guide your care, diagnose and treat complex health problems, create plans of care, and support other members of your team.  In addition they review your outside records and consult with your specialists as needed to coordinate your care.

Nurse Practitioner

These primary care providers diagnose and treat complex and acute health concerns and work collaboratively with physicians to identify the best plan of care for you.

Nurse practitioners are registered nurses with advanced academic and clinical education at the graduate level.  A master's degree in nursing, along with specialty education, enables nurse practitioners to diagnose and manage many common illnesses, both acute and chronic.

Medical Assistants

These providers are instrumental in helping patients feel at ease while visiting our practice.  They will prepare you for your appointment, coordinate your preventative screenings, provide education, give vaccinations, and other medical procedures including taking vital signs, EKGs, ear irrigations, and INR checks.

Administrative Professionals

These team members provide an important role with welcoming you: coordinating appointments, guiding you through the complexities of medical insurance and the healthcare system, and assisting with medical billing.

Stacey Hopper, NP received her Master's Degree in Nursing from the University of California, San Francisco in 2000.  She is board certified as an Adult Nurse Practitioner by the American Academy of Nurse Practitioners (AANP).  

As a Nurse Practitioner, Stacey is an expert in health promotion, disease prevention, health education and counseling, as well as diagnosis and management of common and complex acute and chronic diseases.  Stacey will be working closely with and under the supervision of  Dr. Betz to provide our patients with the comprehensive care and quality of service they are used to receiving.

Stacey relocated to Phoenix in 2013, after spending most of her life in California.  In her spare time, she enjoys doing almost anything that involves being outdoors and being active.  She also practices yoga, is a huge animal lover (especially dogs), and appreciates any chance she gets to continue to explore all that Arizona has to offer with her family and friends.

Stacey is passionate in her belief that empowering people to be active participants in maintaining their health and/or managing their chronic medical conditions is vital to providing good health care, and she truly enjoys helping people understand how all aspects of their daily life can have an impact on their health.
