Few firms have the caliber of skill required to bring a 360° perspective to every engagement the way SLBiggs’ professionals can. Over 40 years of experience handling literally thousands of cases has allowed us to develop the specialized knowledge and expertise required to quickly grasp the big picture, identify the critical aspects of a case that are likely to elude less seasoned professionals, and bring about a favorable, cost-effective outcome for our clients. As a niche practice within a large firm, we are able to deliver the highly responsive, industry-specific expertise our clients expect and deserve, with the depth of talent and resources required to handle major, complex cases.

Partner and staff backgrounds include appointments as bankruptcy trustee for the Central District of California, Subchapter V Trustee for Region 19 (Colorado and Wyoming), and receiver in both federal and state courts, expert witness testimony in Federal and California Superior Courts, national and international forensic investigations and valuations of closely held corporations, partnerships and limited liability companies.
