Medical Team

Dr. Angelo Ciminiello is the true definition of a sports medicine specialist. He is fellowship trained in sports medicine, served as assistant team physician to the Boston Celtics and Northeastern University, and is the former director of Orthopedic Trauma at Danbury Hospital. Dr. Ciminiello's combination of superior medical training, experience as a knee and shoulder surgeon, and on-the-field credentials, makes him uniquely qualified to understand the physical demands and psyche of the competitive athlete. As captain of his college's Division I baseball team, he earned numerous scholar-athlete honors while leading the players to a Big East Championship and the NCAA College World Series Tournament.

Dr. Ciminiello believes patients do not need to be high-level athletes to receive high-level care. As a sports medicine subspecialist, he has a deep interest in shoulder and knees injuries, complex fractures, and minimally invasive arthroscopic knee and shoulder surgery. He is the only sports medicine surgeon in the area to perform All Inside ACL Reconstruction. He has authored several articles on rotator cuff repairs and is frequently asked to speak to surgical residents and civic groups on sports medicine. In addition to being the team physician for the FPHL and NAHL Danbury Hat Tricks, Ciminiello works with Ridgefield High School, Bethel High School, and the collegiate NECBL team Danbury Westerners.

Peter Ackerman has been a Physician Assistant for OrthoConnecticut since 2011. He has experience working beside multiple doctors in the office and operating room. Ackerman has assisted in a plethora of diverse surgeries ranging from minimally invasive arthroscopies to total joint replacements of the knees, shoulders, hips and ankles. As of 2015, he is working exclusively with Dr. Angelo Ciminiello, which means Pete will be assisting in all of the physician's office hours and surgeries. This includes assisting Dr. Ciminiello with All-Inside ACL reconstructive surgeries, a new and innovative technique which utilizes arthroscopic instrumentation with smaller incisions and is a less invasive way of repairing a tear so that patients experience less trauma and easier recovery.

With over twelve years of experience in the sports medicine field as an athletic trainer and strength and conditioning specialist, Ackerman has worked as the athletic trainer for both Immaculate High School and New Fairfield High School. Ackerman has also helped organize and implement education clinics for the Western Connecticut Sports Medicine Society along with Immaculate High School.

Ackerman currently coaches little league baseball and stays active himself by participating in obstacle course races as well as playing in a men's baseball league. With Ackerman's experience in sports medicine education, athletic training and being an athlete himself comes full understanding of the demands placed upon an athlete's body and the desire to return to normal day to day activities.

Fascial distortions are corrected with hands-on deep pressure application with measurable, dramatic results. This will help to improve optimal performance while decreasing recovery/rehabilitation time.

Dr. DiLorenzo has worked with a variety of patients such as athletes on the high school and professional level (such as the Danbury Whalers/Hat Tricks), and pregnant women and children.
