About Us

At Pacific Coast Periodontics, periodontists Dr. Sohyun Park and Dr. Mark Wiesen, and their team provide comprehensive periodontal care to adults living in and around the Union Square area of San Francisco, California, and throughout the Bay Area.

Our team provides comprehensive gum treatments, including deep cleanings, gum grafts, bone grafts, and LANAP® laser dentistry. Their years of knowledge and expertise ensure virtually pain-free procedures, quick recovery times, and long-lasting outcomes.

Pacific Coast Periodontics also offers other types of oral health care, including crown lengthening, diagnosis and treatment of periodontal disease, and placement of dental implants. The practice uses advanced technologies and special tools to minimize the invasiveness of certain procedures. That limits the risk of potential complications, allowing for healthy gums and smiles.

The team at Pacific Coast Periodontics loves getting to know patients and sets aside time to understand their unique symptoms and goals. They use this information to develop custom care plans that improve oral health.
