Javier Muniz

I became involved with Operation Walk In 2018. My first trip was to Honduras. I had no idea what was is store for me. What I experienced was something that I will cherish for the rest of my life. I discovered the amazing reward of giving your absolute all and not expecting anything in return.

Dr. Christlieb attended The Medical College of Pennsylvania (now Drexel University) and was inducted into Alpha Omega Alpha National Medical Honor Society upon graduation. He then completed Internal Medicine residency at Allegheny General Hospital in Pittsburgh. He is board-certified in Internal Medicine and is a Fellow of the American College of Physicians.

Dr. Christlieb spent time working with Operation Safety Net in Pittsburgh, caring for those experiencing homelessness by providing medical care in multiple settings, including the streets at night and clinics during the day. He also worked managing the medical unit and administering medical care to incarcerated persons in the county prison. “From my earliest memories, I have wanted to be a physician and lead a life of service. I was born in Mexico and grew up as a child of a cardiothoracic surgeon and a cardiac nurse. Residing within The National Institute of Cardiology complex in Mexico City, I lived and breathed the art and passion of medicine. I had a front-row seat witnessing the care and service provided to a diverse population, including the indigent community. These experiences set the stage for fervently pursuing a career of service as a physician.

As a hospitalist, I have many years of experience in the surgical-medical comanagement of patients and have forged close working relationships with my nurse and surgeon colleagues. I was elated, very excited, but most of all grateful to have the honor and opportunity to be a part of the great team providing the wonderful and very needed humanitarian work that Operation Walk brings to the people in these underserved communities.

“….. for the secret of the care of the patient is in caring for the patient.”

Pricila Tressler

My journey with Operation Walk began in 2023, when I was privileged to be invited on my first medical mission. This upcoming trip will be my fourth medical mission with Operation Walk-Honduras, and each journey continues to be transformative—professionally, personally, and spiritually. These missions are not only about restoring mobility through life-changing orthopedic surgeries—they’re about restoring dignity, independence, and hope to individuals and families.

With over a decade of nursing experience spanning Neonatal Intensive Care (NICU), Preoperative, and Post-Anesthesia Care (PACU) settings, I have dedicated my career to delivering compassionate, expert care across life’s most critical moments. Currently, I serve as a Worker’s Compensation Case Manager, where I advocate for injured workers on their road to recovery. My passion for patient care extends beyond the bedside—I’m equally committed to empowering the next generation of nurses through mentorship and education.

As a wife, mother of three, I carry with me a deep sense of cultural pride and purpose in all that I do. My bilingual background has been a vital asset in serving diverse patient populations, and it’s a skill that has only grown stronger through my mission work.

I invite you to be part of this mission. Your donation, no matter the size, directly supports the medical care, supplies, and infrastructure that make these trips possible. Together, we can bring healing across borders and make a lasting impact.

Thank you for your support and generosity.

Hi, I’m Dr. Laura Moore, a board-certified anesthesiologist with seven years of experience. I completed my medical education and training at Wake Forest University, where I built a strong foundation in patient care and furthered my passion for serving others.

Now, I’m so excited to take these skills beyond the hospital walls and use them to make a difference on the OpWalk mission trip. Providing safe anesthesia and compassionate care to communities with limited access to medical resources is a dream come true, and I feel incredibly grateful for the opportunity.

Hello, I am Andrew Kohler, PT, DPT. I’ve been a physical therapist for nine years, with experience in acute care, outpatient settings, and inpatient rehabilitation. One of the most meaningful parts of my work has been serving the Hispanic/Latino community. Being proficient in Spanish has allowed me to connect more deeply with patients, their families, and community leaders.

I’ve had the opportunity to work on international health initiatives in Guatemala and the Dominican Republic. During those trips, I worked alongside orthopedic surgery teams, public health educators, and therapy teams to provide comprehensive care.

This will be my first service trip with Operation Walk-Honduras, and I am excited to combine my clinical skills with my passion for serving underserved populations. It’s a unique opportunity to give back, and I’m looking forward to making a positive impact.

Thank you for your support. These trips would not be possible without your encouragement and generosity.

To be involved with this group was always a dream of mine. I am now please to say that I’ve been fortunate enough to participate in two trips to Honduras with Operation Walk Carolinas. This is the reason I became a nurse, to have the ability to create change in people’s lives for the better.
