Exhibit 99.1

OAK VALLEY BANCORP REPORTS 3rd QUARTER RESULTS

OAKDALE, CA – Oak Valley Bancorp (NASDAQ: OVLY), the bank holding company for Oak Valley Community Bank and Eastern Sierra Community Bank, recently reported consolidated financial results. For the three months ended September 30, 2011, consolidated net income was $1,749,000, while consolidated net income available to common shareholders was $1,177,000, or $0.15 per diluted common share. This compared favorably to net income available to common shareholders of $931,000, or $0.12 per diluted common share for the same period a year ago.

Year-to-date results for the nine months ended September 30, 2011, include net income of $4,364,000 and net income available to common shareholders of $3,371,000, compared to net income of $3,128,000 and net income available to common shareholders of $2,496,000 during the same period last year.

Net interest income remained stable decreasing slightly by $20,000 or 0.3% to $6.3 million for the three months ended September 30, 2011, compared to the same period last year. Year-to-date net interest income increased $182,000 from the previous year to $18.8 million.  The bank’s balance sheet growth, driven by core deposit expansion, and corresponding increases in the investment portfolio, have effectively offset the impact of the decrease in the loan portfolio.

Non interest expense for the quarter and nine month period ended September 30, 2011 totaled $4.2 million and $13.1 million, respectively, and $4.2 million and $12.9 million for the comparable periods in 2010. The year-to-date increase is primarily related to staffing and overhead costs associated with the opening of two branches in 2011.

“It has been a very positive year for Oak Valley Community Bank.  We opened two new locations within the core of our existing footprint, expanding service and convenience for both new and current customers,” stated Ron Martin, CEO.  “Earlier this year, we also

reached a milestone, celebrating our 20 year anniversary and two decades providing a true community banking alternative to our friends and neighbors who appreciate the value of investing in the communities we call home.”

The Company continues to experience solid reductions in non-performing assets.  As of September 30, 2011, non-performing assets to total assets are 1.50%, or $8.7 million, down from 2.00%, or $10.7 million for the same period a year ago.

The provision for loan losses during the three months ended September 30, 2011, was $300,000, compared to $1.0 million during the same quarter of last year. However, in the last 12 months the ratio of loan loss reserves to gross loans has been increased from 1.88% to 2.26%.

During the quarter, the Company repaid the Treasury Capital Purchase Programs funds.  This resulted in the accelerated accretion of $361 thousand associated with a corresponding warrant to purchase Oak Valley Bancorp common stock.  The Bancorp concurrently participated in the Small Business Lending Fund, maintaining its strong capital position.

Total assets were $584.0 million at September 30, 2011, an increase of $49.1 million, or 9.2%, from September 30, 2010. The Company’s total deposits were $505.5 million as of September 30, 2011, an increase of $56.6 million, or 12.6% over September 30, 2010.  Gross loans decreased by $17.6 million, to $391.4 million as of September 30, 2011, a decrease of 4.3% from September 30, 2010.

The Company currently operates through 14 branches in Oakdale, Sonora, Turlock, Stockton, Patterson, Ripon, Escalon, Manteca, three branches in Modesto; and three branches in their Eastern Sierra Division, which includes Bridgeport, Mammoth Lakes, and Bishop.
