board certified Family Nurse Practitioner, with over 10 years of experience in the medical field

Meet Stacy Welker MSN, FNP-C

With over 15 years of experience in the medical field, I have dedicated my career to helping patients achieve optimal health through a root-cause, functional medicine approach. As a Functional Medicine Provider and Hormone Specialist, I focus on uncovering the underlying causes of chronic illness, metabolic dysfunction, and hormonal imbalances. I help both men and women optimize their health through bioidentical hormone replacement therapy (BHRT), lifestyle interventions, gut restoration, and regenerative medicine.

My journey in medicine began in emergency medicine and as a first assist in general and trauma surgery, where I gained extensive experience in acute and surgical patient care. However, one defining moment changed the trajectory of my career.

One night, I was called to the emergency department to consult on a critically ill patient needing emergency surgery for a bowel perforation. Though I had seen similar cases countless times, this time, I felt different. I began questioning why such extreme interventions were necessary—why preventative medicine wasn’t being prioritized and why so many patients were presenting with multiple chronic diseases that weren’t well managed. I saw a significant gap in the conventional medical model and felt like I was constantly "putting corks in the dam" rather than addressing the root cause of disease. Burned out and disillusioned, I set out to find a better way.

Through my research, I discovered functional medicine, which completely transformed my perspective on health. I enrolled in the School of Applied Functional Medicine (SAFM), where I completed over 400 hours of intensive education in advanced functional medicine sciences. This training provided a deep understanding of the interconnectedness of the body's systems, allowing me to assess and treat the root causes of chronic disease rather than simply managing symptoms. I learned how imbalances in gut health, hormone function, immune response, and metabolic processes drive disease—and, more importantly, how to reverse these dysfunctions through targeted interventions.

As I applied these principles to my own life—addressing my struggles with insomnia and anxiety—I experienced profound changes firsthand. It was then that I knew I wanted to shift my focus entirely to functional medicine.

I founded Alaya Health & Wellness to help patients take control of their health by addressing root causes rather than just symptoms. Over the years, I have worked with patients to:
✔ Reverse type 2 diabetes
✔ Optimize gut health
✔ Support immune function
✔ Balance hormone disorders and restore hormonal harmony in both men and women
✔ Put autoimmune diseases into remission

As a Functional Medicine Provider and Hormone Specialist, I am passionate about helping patients reclaim their health by addressing hormonal imbalances that impact energy, sleep, metabolism, mood, and overall well-being. Through bioidentical hormone replacement therapy (BHRT), peptides, gut optimization, and personalized functional medicine protocols, I help my patients achieve hormonal balance naturally while also addressing the root causes of metabolic dysfunction, gut disorders, and inflammation.

One of the most rewarding aspects of my work has been empowering patients with the knowledge that what they eat, how they sleep, the toxins they’re exposed to, and how they manage stress all directly impact their health. By educating my patients, I’ve witnessed incredible transformations and rekindled my own passion for medicine.

My mission is to provide personalized, science-backed, and holistic care that helps people heal, thrive, and truly understand their health. Through my work in functional and regenerative medicine, I am dedicated to changing the way healthcare is delivered—one patient at a time.
