About StoneTurn

StoneTurn was founded in 2004 as a highly collaborative, people-focused advisory firm to help clients navigate a post-Enron world without the conflicts and entanglements that were so emblematic of the time. The firm advises companies, their counsel, and government agencies on regulatory matters, risk and compliance issues, investigations, and business disputes.

Over the past fifteen years, StoneTurn has evolved to serve changing client needs. As the firm deepened its expertise, it has also expanded its presence. In 2008, the firm expanded into Europe with the opening of its London office to help multinational organizations and their counsel address significant challenges posed by the global financial crisis.

StoneTurn continues to be agile and responsive in adopting new strategies to thrive in perpetually changing markets. In 2018, it extended its global reach into Germany, Brazil, and South Africa, positioning the firm to meet new challenges posed by cross-border enforcement actions and emerging corruption threats. Now a formidable global player, StoneTurn maintains its people-first business model to establish and develop lasting relationships with clients.

Turning to the Experts

StoneTurn lends its expertise to domestic and multinational clients in six main practice areas: Litigation Advisory, Investigations, Compliance & Monitoring, Valuation Advisory, Forensic Technology, and Data Analytics. Within each practice, the firm provides a host of highly specialized services. For example, the Compliance & Monitoring practice works with clients to implement proactive compliance programs, respond to incidents of fraud and misconduct, and provide post-incident remediation and monitoring expertise. Clients typically require assistance when faced with anti-corruption violations, construction integrity monitoring issues, regulatory inquiries, and in evaluating the general effectiveness of risks and controls. To every client engagement, StoneTurn consultants bring the firm’s signature people-first approach, a deep level of expertise, and nimble responsiveness.

StoneTurn serves clients across a range of industries, including automotive, energy, financial services, healthcare, retail, telecommunications, and private equity. Many StoneTurn professionals join the firm with extensive industry experience, bringing a unique perspective to every client engagement.

Leaving No Stone Unturned

According to StoneTurn, one of the firm’s essential differentiators is its firm-wide commitment to “leaving no stone unturned.” This sentiment reflects the ethos with which StoneTurn professionals approach every interaction with clients and colleagues. The firm has established itself as a trusted client adviser, and it takes that reputation seriously. Teams are highly responsive, hands-on, and efficient.

Thoroughness, deep expertise, and a focus on open communication allow StoneTurn to deliver value clients in a way that is approachable, yet also effective. The firm invests in culture and professional development to encourage the growth of its people and drive more meaningful client interactions. Above all, the firm engages in a mindset of positivity and respect, always striving to ensure that StoneTurn is an organization’s first call.
