California Sinus Centers Atherton Celebrates 10 Year Anniversary

April 1, 2019 marked the 10 year anniversary of the California Sinus Centers Atherton office! To celebrate this milestone, Dr. Vaughan treated his staff to a weekend getaway in Sonoma, California complete with hand made jewelry for each staff member. The team spent 3 wonderful days reflecting on the past 10 years, getting to the know the Sonoma area, hiking, wine tasting, and doing lots of eating! On Monday, we treated patients to a Krispy Kreme breakfast and cards to share their reflections on Cal Sinus.

Dr. Vaughan and the entire Cal Sinus Atherton team thank all of the patients and providers who have trusted us with their care for the past 10 years (and some even longer!). None of this would be possible without your support. To the next 10 years!

New Central Valley patients are encouraged to establish care in one of our Bay Area locations and continue seeing Dr. Vaughan in the Clovis location for follow-ups.
