Tammy Frost, PA-C, is the founder and lead provider at GRACE Direct Primary Care in Prescott, Arizona. She is a board-certified Physician Assistant with a Master of Science in Physician Assistant Studies, a 3.97 GPA, and more than 30 years of experience in business, family medicine, functional medicine, and whole-person care dedicated to serving patients across Prescott, Prescott Valley, Chino Valley, and Yavapai County.
When patients come to GRACE, they often say the same thing afterward:
“This is the first time I have felt like someone actually listened.”
That’s no accident. It reflects who Tammy Frost is and what she’s experienced.
A Provider Shaped by Her Own Experience as a Patient
Tammy did not arrive at patient-centered care through a philosophy course. She arrived at it through personal experience. You can read the full story about Tammy Frost, PA-C, on page, but the short version is this: she was once the patient who raised concerns, asked questions, and was dismissed. Her condition worsened. What could have been treated conservatively required surgery. The harm was preventable.
That experience is not a background detail. It is the reason GRACE exists.
“If my team had listened and diagnosed me correctly, I could have healed without surgery. That experience is exactly why I refuse to let it happen to my patients.”
At 13, Tammy fractured her neck in a serious motor vehicle accident. Recovery took months and taught her something no classroom could: what it feels like to be afraid, uncertain, and reliant on your care team. She brings this understanding to every appointment.
Generations of Arizona Healers
Tammy’s connection to medicine runs deeper than her own credentials. Her family has been serving the healthcare needs of Arizonans since before Arizona was a state serving patients during Ariziona’s early territorial days.
That is not a figure of speech. Her great-great-grandfather established one of the earliest medical institutions in the Gila Valley. Physicians on both sides of her family served families across Navajo County, the Chiricahua Mountains, and some of the state’s most remote regions. Her fourth great-grandmother was described as a natural-born healer in the 1800s in Navajo County, AZ.
What makes this remarkable is that Tammy found her calling on her own. She did not know about most of these family connections until recently. Her journey into medicine was organic. Discovering that legacy made it even more meaningful.
Generations of healers. One Physician Assistant is carrying it forward in Prescott, Arizona.
The Loss That Drives Her Work
Tammy’s father spent his last days in Beaver Dam, Arizona. This remote town of fewer than 1,000 people had almost no local healthcare options. A simple blood test could have detected his declining kidney function in time to act. Instead, diagnosis came after kidney failure, and he had to move to Phoenix for treatment. He survived one more year.
That loss is not abstract for Tammy. It is personal and present in every decision she makes as a provider.
“Anyone who lives in an area without adequate healthcare choices suffers, and I know this firsthand. I am committed to helping all those who need affordable, quality healthcare.”
This loss is not abstract to Tammy. It shapes every decision she makes as a provider. It drives her practice style. Direct Primary Care removes barriers that delayed care for her father. There is no insurance friction for routine visits. Patients have direct access to a provider who knows them, with transparent costs. This care helps catch problems early.
What Tammy Brings to Every Appointment
Tammy earned her Master of Science in Physician Assistant Studies from King’s College. She also earned a Bachelor of Science from Northern Arizona University, graduating Summa Cum Laude with a 3.97 GPA. She is NCCPA Board Certified, has an Arizona PA license, a DEA registration, and certifications in ACLS, BLS, and aesthetics.
She is also a member of four national honor societies and has received scholarships, including the prestigious NHSC Scholarship and the Gold Axe Award. In 2025, she was recognized as one of the Top 3 in Yavapai County for Primary Care in the Best of Yavapai awards.
But credentials are the starting point, not the whole picture.
Tammy brings a holistic, integrative approach to each clinical area. She looks beyond symptoms and asks about the whole person: sleep, stress, gut health, hormones, emotional state, and life history. Her clinical focus areas include:
- Family medicine and acute care
- Functional and integrative medicine
- Neurocognitive health
- Gut health and autoimmune disorders
- Adrenal and thyroid health
- BioIdentical Hormone Replacement Therapy and Testosterone Replacement Therapy
- Non-opioid pain management and chronic inflammation
- Hair restoration with TED
- Anti-aging services and preventive medicine
This range reflects GRACE’s broader philosophy: most conditions have root causes. Finding them takes time and curiosity. It requires a provider who asks questions that most 10-minute appointments never reach.
A Different Kind of Primary Care
GRACE is a Direct Primary Care practice. Tammy does not bill insurance for any office visits. Patients pay a monthly membership fee for unlimited visits, same-day or next-day access, no office visit co-pays, no hidden fees, and direct access to Tammy and her care team. GRACE serves Prescott, Prescott Valley, Chino Valley, and Yavapai County.
Many members still carry traditional insurance for labs, imaging, specialists, hospital care, and emergencies. Others have no insurance and benefit from GRACE’s discounted cash pricing for many lab tests. Either way, the model removes friction that blocks patients from the care they need. The result is what Tammy intended: a practice where patients feel heard, appointments are unhurried, and the provider knows your story before reviewing your chart.
What Patients Say
Patients say their experience at GRACE is unlike anything they expected from healthcare. It is not rushed, not transactional, and not confusing.
Just clear, steady, relationship-based care from an attentive provider.
That is Tammy. And it is why GRACE exists.
