Hand, Wrist & Elbow

The hand, wrist, and elbow are intricate structures that are prone to a number of conditions and injuries as we go about our day-to-day activities. Our doctors work closely with patients who suffer from problems of these upper extremities, searching for the best possible solution for their unique needs. If you are experiencing hand, wrist, or elbow symptoms that interfere with your daily life, we encourage you to use our website as a resource for you to conduct research and to contact us with any questions you may have, or to schedule an in-depth consultation.


Our shoulders go through a wide range of motions that can be severely affected by a variety of problems. Whether you suffer from a chronic condition that has developed over time, or you have experienced sudden trauma that has injured your joint, our upper extremity specialist will help relieve your symptoms through the least invasive treatment options possible. Before you know it, you can be on the road to recovery and feeling more like your healthy self.

Hip & Pelvis

Injury, overuse, and normal wear can all cause a variety of symptoms in the hip and pelvis area. While some can improve with rest, others may require more advanced treatment, such as injections, total hip replacement, orthoses, or surgery. Dr. John Hoffman, our hip specialist, can help you find the best treatment for your specific hip and pelvis concerns, often utilizing minimally-invasive options for less downtime.


The knee is especially prone to injury, due to the significant force applied when playing sports. It can also develop problems from wear or overuse, which can create the need for surgical intervention. If you experience pain or discomfort in your knee, you should consult a medical professional to learn of the cause. By doing so, you can understand what the best form of treatment is and how to prevent your problem from worsening. Dr. Hoffman and Dr. Mendel, can help you find the best treatment option, utilizing minimally invasive options, to get you back to life quicker.

Foot & Ankle

Our foot and ankle surgeon, Dr. Tuvi Mendel, performs minimally-invasive foot and ankle procedures to help you get back to your normal activities with the least amount of downtime possible. Since the entire weight of the body, as well as additional stress, is placed on the foot and ankle, it is one of the most commonly injured areas. It is important you seek orthopaedic attention if you experience abnormal sensations or pain to keep your joints healthy and working properly.

Back & Neck

The symptoms of various back and neck problems can affect how the rest of the body functions. To relieve your discomfort and help you resume your normal activities, our spinal surgeon, Dr. Michael Dolphin, can diagnose your back and neck conditions and recommend the best treatment options for you. Non-surgical treatments are always the first to be considered, but minimally-invasive surgery is also available if you have a more complicated condition.

Joint Replacement

Your joints are a vital part of the human body, and when they’re not working properly, your day-to-day activities can seem impossible. While some conditions can be treated with non-surgical treatment, others may only improve with surgery. Dr. John Hoffman and Dr. Tuvi Mendel strive to find the least invasive treatment options possible, and only recommend surgery if it has significant potential at improving your joint problem.

Sports Medicine

Sports-related injuries require unique attention to not only repair damage, but also to help the area heal correctly to prevent future problems. By receiving a proper diagnosis and getting the appropriate treatment, you can preserve your body for a healthy future and lower your risk of recurring injuries to the same area. At our Sports Medicine Center, Dr. John Hoffman, Dr. Tuvi Mendel and Dr. Kristyn Darmafall will provide you with the latest advancements in orthopaedic care, helping you get back to what you love sooner.
