Welcome to the Practice

Dr. Connie Oh and Dr. Donald Brown are specialists in Periodontics and Implantology. Our practice specializes in treatment of the supporting structures of the teeth, including bone and gum tissue surrounding the teeth. We deal with the placement of dental implants, non-surgical and surgical treatment of diseases of the gums and bone, and procedures that can aesthetically enhance your smile.

Coordinated care

We work closely as a team with your referring dentist, but a referral by a dentist is not required to become a new patient. We welcome referrals from patients and friends of the practice. If you are in need of a general or restorative dentist, we can provide you with the names of some of the excellent dentists we work with.

We are extraordinarily proud of our team, which consists of caring and dedicated professionals. We communicate with you and your dentist, ensuring that your clinical, periodontal, and administrative needs are met as efficiently and smoothly as possible.

Our goal is to make you feel comfortable and relaxed. We are here to listen to you and to help provide solutions leading to your better health. Periodontal treatment is a partnership between your periodontist, your dentist, any other treatment providers, and you. If you are anxious about receiving care, we have a variety of sedation options available to make your treatment as easy as possible.

Initial appointment

Your initial appointment will consist of an evaluation and explanation of your specific concerns. We strive to give you as much information as we can, so you can make an informed decision about your treatment.

Please assist us by providing the following information at the time of your consultation:

  • Your referral slip and any x-rays, if applicable;
  • A list of medications you are presently taking;
  • Your insurance card, if applicable, along with a photo ID.


If you have any questions or concerns before visiting our office, feel free to give us a call at (510) 522-3545. We look forward to meeting you!
