Michael Fahlikman brings a depth of experience to his tax position at BDCo. Originally from Queens, New York, Michael is a graduate of Queens College of the City University of New York where he holds a Bachelor of Arts in Accounting and Information Systems. He has had experience working in both corporate roles and public accounting firms which has given him a wealth of insights into the needs of businesses of all kinds. His title reflects his role at the firm and his passion for the animals at the Wake County North Carolina SPCA shelter where he is a trained volunteer. You will find him spending most of his free weekends there with 4 or 5 dogs at a time. We are glad he chose to pursue accounting as a career rather than zookeeping, which was his aspiration at one time. Michael’s favorite place is Asheville, North Carolina where he enjoys wine tasting at the Biltmore and exploring the scenic trails of the Blue Ridge mountains. Michael is a CPA, licensed by both the the New York State Board of Public Accountancy and by the North Carolina State Board of CPA Examiners.

Dawn Marshall is a Napa native.  She briefly left the Napa Valley for a sojourn to Miami, Florida but returned to Napa to begin her professional career. Her first job was in a florist, before moving to high-end hospitality, then winery accounting and for the past 17 years she has been serving in a number of different roles in city government, culminating in the role of Human Resources and Administrative Manager. She is a two time recipient of “Award of Financial Reporting” by the Government Finance Officers Association. When she’s not helping “humans with resources”, she is likely to be gardening, quilting, or arranging items in her home to be more aesthetically pleasing. Dawn is the mother of 3 children – 2 sons and a daughter who all seem to have inherited some of her creative abilities. As a young woman, Dawn went off to purchase her first automobile, a Renault, at a local Napa automobile dealer. While she was unsuccessful in securing her dream automobile, she ultimately walked away with a first date with her now husband of 29 years.

He graduated Summa Cum Laude from Cal Poly San Luis Obispo where he also earned the College of Agriculture Academic Excellence Award.  He holds a Master of Professional Accountancy from California State University in Northridge, California.

Ricardo’s title reflects his competitive nature and his role at the firm while paying homage to his alma mater, the Cal State Northridge Matadors.  It also reflects a “no bull” mindset when it comes to tax work. Had he not found his way to accounting, Ricardo might have applied his research skills to a career teaching history.  He is excited about applying his agricultural insights and expertise to the wine industry.

Summer joins the BDCO tax team remotely from her home in Montana. After experiencing 4 previous tax seasons, she has a passion for tax planning and still gets excited about IRA to Roth conversions as a tax-saving strategy. (Be sure to ask her.) A graduate of North Dakota State University, Summer majored in accounting and minored in fraud investigation and found her way to accounting by accident. She was headed towards a career in law enforcement until she took that first accounting class and discovered a new passion. When Summer isn’t focused on taxes, she is an avid animé fan and appreciates the teachings that are delivered by its profound characters.  While she had the good fortune of spending a number of her childhood years in the beautiful country of Bahrain, her ideal vacation destination is Japan during the cherry blossom festival.   Summer is a CPA licensed by the  Montana Board of Public Accountants.
