Comfort and convenience are the hallmarks of Joint Preservation Institute's office operations. To ensure your convenience, below is the information you need about our hours, location, appointment scheduling, insurance acceptance and billing.


We know you have many choices when choosing an orthopaedic and sports medicine clinic in Northern California. We have made requesting an appointment a simple process via our Web site. If, for any reason, you cannot keep a scheduled appointment or will be delayed, please call as soon as possible. Charges may be incurred for appointments cancelled less than 24 hours before scheduled appointment time.


Our office accepts a variety of health plans. We are in network for most health plans.

Out of network

Being out of network indicates that we do not have a contract with a given insurance company. With out of network plans, patients pay at the time of service. We then provide patients with the necessary forms to obtain reimbursement from their insurance companies. In many cases, the out of pocket fees for patients are nearly the same for in network and out of network care. Our staff is very knowledgeable about this process and can help guide our patients through it.

Our Staff

The goal of our staff is to provide the most pleasant and comfortable way for you to receive the optimal care for your orthopaedic issues. We will make every attempt to return your calls promptly.

We encourage you to contact us if you have questions about the services that we offer. We in particular are happy to provide free consultation in complex issues pertaining to hip, knee, post-traumatic, and deformity related issues.

The most efficient way to evaluate your case is to have you obtain your medical records and radiographic studies in CD format and mail them to our office with a short introduction letter. We will review them and contact you, usually within one week.
