ATLANTIC, IA – Cass Health Orthopedic Surgeon Dr. Matt Weresh, a distinguished physician with more than 30 years of service in Iowa, announced his retirement effective May 2026. Dr. Weresh will complete his final orthopedic surgeries at Cass Health during the first week of April.

Dr. Weresh relocated his practice to Cass Health in 2017 and has since provided expert care in a wide range of procedures, from complex hip and knee joint replacements to general surgeries. He was a pioneer in the region—the first orthopedic surgeon to serve central Iowa with specialty training in trauma and fracture care, areas which remained primary interests throughout his career. His impactful work has been published in several national articles and presented at numerous conferences in the fields of hip, knee, and general trauma/fracture care.

“Dr. Weresh’s impact on orthopedic care in this region cannot be overstated,” said Brett Altman, Chief Executive Officer at Cass Health. “His expertise, particularly in trauma and joint replacement, has served our community exceptionally well. While we will deeply miss his contributions and dedication, we are well-prepared for this transition and excited to announce a significant expansion of our orthopedic capabilities to meet the growing needs of our patients. Thanks to Dr. Weresh pioneering the way, Cass Health will be offering our most robust orthopedic care with six 5-star professionals much like Dr. Weresh.”

Cass Health has been proactively planning for Dr. Weresh’s retirement and is expanding its orthopedic team to offer more comprehensive services. This strategic expansion ensures continuity of high-quality care and introduces new specialized expertise.

Currently, the orthopedic team includes Dr. Dan Hatz, Dr. Caliste Hsu, and Zachary Hollingsworth, PA-C. Dr. Hatz provides comprehensive orthopedic care including hip, knee, and shoulders. Dr. Hsu specializes exclusively in hand and microvascular procedures including carpal tunnel release, arthritis management, and traumatic injury repairs. Hollingsworth is a dedicated physician assistant to the orthopedic team, specializing in surgical and inpatient follow-up care, assisting in orthopedic and general surgeries, and coordinating comprehensive patient evaluation and clinical orders.

Cass Health also recently partnered with MD West ONE, the region’s largest private practice for orthopedics, neurosurgery, and spine care. Four physicians from MD West ONE will begin practicing at Cass Health in February 2026:

• Dr. Todd Sekundiak, Dr. Kimberly Turman, Dr. Charles Rosipal, and Dr. Jordan Lacy.
• Dr. Todd Sekundiak is a nationally recognized leader in joint replacement, who specializes in minimally invasive and robotic-assisted surgeries, including the innovative “Jiffy Knee” procedure.
• Dr. Kimberly Turman is an expert in arthroscopy and reconstructive surgery of the knee, shoulder, and hip, and has a particular passion for sports medicine.
• Dr. Charles Rosipal has advanced fellowship training in shoulder instability and rotator cuff repair.

Additionally, Neurosurgeon Dr. Jordan Lacy will return to Cass Health. Specializing in complex spine conditions, Dr. Lacy provides expert diagnostics and surgical procedures for back and neck health. “This next chapter of orthopedic care at Cass Health is really exciting for us and our patients. We are deeply grateful for Dr. Weresh’s service here, and we look forward to working with a team that continues his legacy of excellence,” said Altman.
