What Straussner, Sherman, Lonne, Treger, Helquist does

Straussner, Sherman, Lonné, Treger, Helquist, Krupnik (operating under the DBA "Straussner Sherman" and branded as SSLTHK) is a privately held California specialty law firm founded in 2004 by Aaron Straussner and Julie Sherman and headquartered in the historic Van Nuys Library building at 14555 Sylvan Street, Van Nuys. The firm's practice is structured around three core service areas: workers' compensation, disability retirement, and personal injury representation, with the overwhelming majority of work focused on California public safety officers (firefighters and police officers) and their families. The firm maintains active engagements in highly specialized regulatory domains including California Labor Code 4850 benefits, presumptive injury law (notably cancer and heart trouble presumptions for safety personnel), department-union-based alternative workers' compensation carve-outs, and industrial disability retirement proceedings through systems such as LACERA.

The business model is professional services-based, combining contingency fee arrangements (primarily for personal injury matters), hourly billing (for workers' compensation representation), and a free initial consultation funnel. Client acquisition is community- and union-led rather than performance-marketing-driven: partners serve on the boards and advisory committees of more than ten safety officer organizations, unions, and foundations, and have provided legislative testimony before the California state Assembly and Senate on workers' compensation law. The firm operates as a partnership of seven Senior Partners, one Partner, four Associates, and one Hearing Representative, with no external institutional investors, parent company, or subsidiaries. Revenue is not publicly disclosed. Customer segments are vertically segmented around safety officers (primary), families of safety officers (secondary), and civilians injured on the job (tertiary), all served across Los Angeles, Orange, Ventura, San Bernardino, and Riverside counties. The firm has earned continuous Southern California Super Lawyers recognition since 2009 and has produced multiple attorneys certified as Legal Specialists in Workers' Compensation Law by the California State Bar.

Emerging players

• Allsup: National Social Security Disability Insurance and claims representation firm serving injured individuals; adjacent to Straussner Sherman's disability retirement practice in target customer (injured workers) and revenue model (contingency advocacy).
• The Advocator Group: Disability and leave-management advocacy firm serving employers and claimants; comparable because it competes for the same 'helping injured workers obtain benefits' mandate that underpins Straussner Sherman's disability retirement practice.
• Binder & Binder (now CIGA / individual claimants): Historically large Social Security disability representation firm; a like-for-like disability-claims advocacy peer whose business model (contingency advocacy for injured individuals) mirrors Straussner Sherman's disability retirement and workers' comp practice.

Broad incumbents

• Engstrom, Lipscomb & Lack: California-based workers' compensation defense firm with offices across the state; a direct counterparty in WC litigation and a structural mirror of the applicant-attorney niche Straussner Sherman occupies.
• Demler, Armstrong & Rowland: California workers' compensation and employment law defense firm; comparable because it operates in the same Southern California WC jurisdiction and applies pressure on applicant-side firms.
• Gordon Rees Scully Mansukhani, LLP: Large national law firm with one of the largest workers' compensation defense practices in California; comparable because it litigates workers' comp and related casualty matters throughout California against plaintiff-side firms like Straussner Sherman.
• Schaar & Frost: Long-standing California workers' compensation defense firm; comparable in geographic and practice scope, and an indirect competitor via employer/insurer-side representation.
• Michels & Ransdell: Established California workers' compensation defense firm representing insurers and employers; comparable in that it operates in the same California WC adjudicatory system and frequently opposes firms like Straussner Sherman.

Direct peers

• Rose, Klein & Sarli: California-based workers' compensation applicant-side firm; directly comparable as a boutique representing injured workers — including public-safety clients — across the same Southern California jurisdiction.
• Marcari, Russo & Bell: Plaintiff-side personal injury and workers' compensation firm operating in California; directly comparable in contingency-driven representation of injured workers, including public-safety-adjacent claims.
