Our Physicians

Both Dr. Fenzl and Dr. Stoll were born and raised in WNY, and are graduates of Hamburg High School.
They are the sons of physician fathers who provided health care to our community for over 50 year. Drs. Fenzl and Stoll have worked together for 25 years, and now provide Radiology services to Lakeshore and Tri County Hospitals 24 hours per day, 7 days per week, 365 days per year. They stand true to their committment to not employ any outsourcing of radiology interpretation to unfamiliar radiologists outside the community. Drs. Fenzl and Stoll are always available to provide diagnostic imaging interpretation to inpatient, outpatient and emergency room patients.
