CPA firm at 7755 Fay Ave Suite D, La Jolla, CA 92037, between Silverado Street and Kline Street in La Jolla Village. Founded in 1996 by principal CPA Mark E. Leinenweber, the five-person firm has served La Jolla individuals and businesses for nearly three decades with tax preparation, tax planning, bookkeeping, business consulting, and payroll — open Monday through Friday 9am–5pm. Small business owners who need both tax preparation and outsourced bookkeeping under one roof can keep both at Leinenweber, making it a practical one-stop for lean operations that don't want to coordinate across multiple providers. Clients requiring audit capability or financial statement attestation beyond the scope of a five-person firm should look to Lavine Lofgren Morris & Engelberg at 4180 La Jolla Village Drive — a 12-CPA firm handling audits, reviews, and compilations since 1985. For a solo CPA practice with estate and trust specialization nearby, Tim Austgen CPA has operated from Prospect Street since 1991.
