WALNUT CREEK, Calif., Jan. 11, 2023 /PRNewswire/ -- TYS, LLP, an accounting firm with offices in California and New York, has announced several leadership changes. Glen A. Thomas, CPA, and Lori Lefkowitz have retired; Doris A. Rankins, CPA, has been promoted to Partner.

Doris joined the firm in 2018, bringing over 20 years of public accounting experience to the team, including multi-state taxation and taxation of C corporations, S corporations, and Partnerships of all sizes with a specialization in closely-held businesses. Doris also has extensive experience in rental real estate and the application of tangible property regulations.

As a new partner at TYS, Doris’ experience and skillset are valued additions to the leadership team. “We’re committed to ‘thinking forward’, something we believe benefits all of our clients, and for that, we rely on the vast experience of our leadership team,” says Chief Operating Officer Melissa D. Wallace, CPA.


The move is an exciting one for the firm, as TYS continues to expand its portfolio in real estate and corporate taxation. “As Doris moves into her new partner role, we know that she will continue to provide exceptional service to our clients, and she will be an even greater asset to TYS,” Melissa continued.
