Agnesian HealthCare’s Bone & Joint Health is growing with the opening of a new site at 250 Corporate Drive in Beaver Dam, which has convenient access directly from Highway 151. They will be sharing space with the Beaver Dam Chiropractic Clinic. The clinic is scheduled to open Monday, September 17.

Bert Callahan, MD, orthopedic surgeon, and Luke Lentscher, PA-C, an orthopedic certified physician assistant, specializes in the diagnosis and treatment of diseases and injuries of the bones, joints, ligaments, tendons, muscles and nerves of the body.

Dr. Callahan has been a fixture in the Beaver Dam, Columbus and Waupun communities for more than 20 years. He most recently served at Ripon Medical Center, and now sees patients at Waupun Memorial Hospital.

His specialties/services include: arthritis, arthroscopy, carpal tunnel, computer-navigated knee replacement, elbow disorders, fracture care, joint replacements (hip, knee, shoulder), rotator cuff injuries, shoulder instability/pain, sports medicine and trigger finger.

“After more than 20 years of practice, I have a great deal of experience in knee and hip replacement, and knee and shoulder arthroscopy,” according to Dr. Callahan. “Additionally, I have treated many patients with hand problems, such as carpal tunnel syndrome and trigger finger, as well as common adult and pediatric fractures.”

Dr. Callahan earned his medical degree from St. Louis University School of Medicine. After that, he served with the U.S. Army as an officer in the Medical Corps for nine year, including five years of orthopedic surgery at the Fitzsimons Army Medical Center in Aurora, Colorado. He also served two years as a flight surgeon in Wiesbaden, Germany, and two years as a staff orthopedic surgeon at Bassett Army Community Hospital in Fairbanks, Alaska. 

He is board certified in orthopedic surgery, and is a fellow of the American Academy of Orthopedic Surgeons.

“I enjoy most getting to know patients and assisting them on their path to restore function,” Dr. Callahan says. “I appreciate the opportunity to listen to patients and learn about their lives and interests and family. It is very important for patients to be involved in their own care, and to understand fully the problem(s) they are facing, and the options for treatment, including the advantages and disadvantages of each treatment.”

Lentscher is a graduate of Taylor University in Upland, Indiana, and earned his Masters of Medical Science in Physician Assistance Studies from Midwestern University in Downers Grove, Illinois. He is a member of the American Academy of Orthopaedic Surgeons (AAOS) and certified by the National Commission of Certification of Physician Assistants (NCCPA).

A resident of Beaver Dam, Lentscher is married with three children. He enjoys boating, basketball and soccer, and wakeboarding.

“I’m excited to work with patients closer to home in our local community,” according to Lentscher. “I treat all my patients as I would want to be treated, and I take the time to listen to them and understand what they are trying to get out of treatment.”
