Founder | CEO | CMO | ThuZar Maung, MSN, APRN, FNP-C
My name is ThuZar Maung, and I’m proud to call myself a Mixed with Indian & Burmese SouthEast Asian-American Board Certified Family Nurse Practitioner and founder of Treeva Hormone Health. But my journey to this point has been everything but easy—and I wouldn’t change a thing.
I was born and raised in Burma (Myanmar), where my parents instilled in me the values that guide everything I do today: stand by what’s right, give generously, be kind, never lie, never steal, and never cheat. My father was a remarkable provider who supported our entire extended family, and though my mother only attended school until fifth grade, both of my parents emphasized the importance of education and doing the right thing. I was the youngest of three siblings—and also the most responsible when it came to caring for my parents. That responsibility, along with my independent spirit, shaped who I am.
In 2002, I arrived in the United States with my then-husband. We have two children together. After our divorce in 2007, I found myself a single mother, with no family in the U.S., barely able to speak English, attending ESL classes at Phoenix Community College, and with zero dollars in my bank account. My children were just 3 and 1.5 years old at the time, and I had no one to lean on.
What I did have, though, was determination. I worked multiple jobs, raised my children, supported my parents from afar, and pursued my education step by step—often with very little sleep and a lot of sacrifice. I’ve worked in nearly every healthcare setting you can imagine: emergency rooms, intensive care units, correctional facilities, home health, —and eventually earned my Master of Science in Nursing, graduating with distinction through Northern Arizona University and provided care to Veterans for their compensation and disability exam, teaching as an adjunct professor, and built Men’s health clinic from ground level to be a successful clinic while also providing care at the Urgent care settings.
Along the way, I discovered my true passion: helping people feel better from the inside out through hormone health and holistic wellness. That’s what led me to create Treeva Hormone Health, a practice built on compassion, science, and the belief that nothing is impossible if you work hard and lead with purpose.
I don’t come from privilege. Everything I have today has been earned through sweat, tears, and relentless hard work. I don’t aim to be rich—I just want to give, heal, and make a difference. Whether you’re here because you’re feeling off, tired, unseen, or unheard—know this: I’ve been through darkness too, and I will walk with you toward your best health, one step at a time.
Chief Operating Officer | Sean Vieira, BSN, RN
With over two decades of experience in customer service, construction, and the demanding world of coal mining, I’ve lived the kind of life that shapes grit, character, and an unwavering work ethic. In 2018, I felt called to pivot — not just to a new career, but to a mission: making a deeper impact on people’s lives through healthcare.
I began my journey toward nursing by completing prerequisites and diving into EMT training while awaiting admission to nursing school. By 2020, I was a certified EMT and working in the Emergency Room, where I developed a sharp instinct for high-pressure situations while earning my BSN. After graduating in 2023, I joined the ER nursing team full time — where I've spent the last several years mastering critical care, mentoring new nurses as a Preceptor, and leading operations as Charge Nurse. I’ve learned the power of teamwork, communication, and precision in moments when every second matters.
Now, as Chief Operating Officer of Treeva Hormone Health, I bring this same dedication and clarity to a new purpose: transforming lives through innovative, patient-centered hormone care. My passion lies in building systems that empower our team to deliver exceptional care — and in helping every patient feel seen, heard, and supported on their wellness journey. I’m proud to stand alongside my future wife and visionary founder, ThuZar Maung, as we grow Treeva into a national leader in hormone health, sexual health and overall health.
