Jose Christlieb

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. He has been practicing as a hospitalist since 1999 and served as hospitalist program director at Westmoreland Regional Hospital and subsequently at St. Clair Hospital in Pittsburgh.

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.”

Paul Coleman

Paul Coleman is the lead organizer for the OpWalk Carolinas trips. His involvement with Operation Walk began in 2014 when he first participated in humanitarian trips with OpWalk Denver. While he has accompanied the Denver team on several occasions, it only took that single, first trip for him to immediately realize the rippling impact of helping just one individual begin to walk pain-free.

Since that initial trip more than a decade ago, he has helped the OpWalk Carolinas chapter not only launch but to grow and continue to impact lives globally these past several years. He recognizes, though, that this is more than just operating on someone. These humanitarian efforts are about freedom – freedom from pain, freedom to move, and freedom to live a more fulfilling life.

Samantha Creamer

I have been so fortunate in my own life, and I am excited to be able to give back as a new member of Operation Walk Carolinas. The trip to Honduras in 2026 will be my first ever medical mission, and I have no doubt it will be life changing. It will be an honor to be a part of enacting heartfelt and immediate change in a community of need along with a team of volunteers driven by the same values. When I started working in joint replacement for my first physician assistant job 12 years ago, I never could have imagined I would be able to take those skills around the world with the same goal of helping a patient reduce their pain, increase their function, and most importantly, improve their quality of life. Thank you to all those who work tirelessly on the organization and execution of these trips, and thank you to all those who donate to allow these missions to continue!

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.

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.

Hi there! My name is Carlie Turman PT, DPT and I am the lead physical therapist for the 2026 Operation Walk Rehabilitation Team. I received my Doctorate in Physical Therapy in 2016 and I have been a physical therapist for nine years with experience in acute care, skilled nursing homes and home health.

I’ve been fortunate to participate in international medical mission trips to Haiti, and this marks my third trip to Honduras with Operation Walk. It’s a true honor to be part of such an incredible organization. Our team is made up of exceptionally skilled and compassionate medical professionals who generously volunteer their time and expertise to make a lasting difference—far beyond the communities they serve every day.

As a physical therapist, I’m passionate about giving back and using my skills to help restore mobility, independence, and hope. Our rehabilitation team is especially excited to empower patients in Honduras by providing hands-on physical therapy and sharing the latest in post-operative rehabilitation practices through education and training.

Thank you for your support. None of these trips would be possible without the support from our friends, family and community!

Sarah Mathis

Hey friends!

I am Sarah Mathis PT, DPT, and I will have been a PT for 10 years by the time we go on our next Honduras trip!

This will be my 2^nd trip with the Operation Walk Carolinas team.  I had been on missions trips in the past, including a clinical rotation during PT school in Belize, so I was extremely excited when I first learned about Operation Walk from friends at Atrium who had been on past trips.  I was honored to be a part of the team last year, and I am so excited to be invited back for the 2024 trip.

Last year we had 48 patients, with 53 total joints performed, and too many lives (including mine) were changed to even count.  I fell in love with the whole experience, especially the love and gratitude the people of Honduras shared.  I came back humbled and inspired, and on a continuous search for ways I can give back when I have been blessed with so much.

None of these trips would be possible without the support from our friends and family, who prayed for our safety and success, checked in on us, and financially supported us along the way.  Thank you, thank you, thank you for your love and support!
