Take Better Risks.
Make Better Decisions.
Deliver Better Results.

      – The Shull Method

Human Performance and Risk-Decision Consultants

We revitalize professional investors, invigorate professional athletes, and inspire CEOs – all by honing their personal psychologies of risk. 

The Shull Method, our signature consulting framework, relies on the latest brain research on how humans perceive, judge and decide. Understanding this on a practical level routinely allows us to resolve the mysterious mental challenges of slumps, burnout, motivation and resilience. Our distinctive approach produces results that are unmatched in the performance and risk-taking fields.

Let us help you ReThink the pivotal elements of risk decision making and performance under pressure. Together, we can develop the extraordinary skills of parsing your intuitions,  sticking with your convictions and more quickly recovering from the inevitable competitive setbacks.

Trading & Investing

Traders, Investors 
Chief Risk and Chief Investment Officers 

Learn how to trust in your own judgment. Understand your convictions. Learn how to recognize valid intuitions and divert impulsive urges. Despite what they say, you are not controlled by cognitive bias.



Athletes, Coaches
General Managers and Owners

Grab a powerful new edge in the pursuit of that mysterious “It” or “X” factor. Sharpen the mental edge you bring to your most pressure-filled competitions and to your toughest risk decisions.



Performers, Agents 
Producers and Directors

Tap directly into your whole psyche – your natural kaleidoscope of fears, frustrations and joys to create, perform, produce or direct even more elegantly than you do now.

So many attendees came up to me and commented that
Denise's session was their favorite of the entire event.  

- ML, Real Vision


Denise has helped me see my past in a way that no one else has, and now I am moving toward my professional soccer career in a way that encourages me. Most of, if not all, of any future success I have will be attributable to Denise.

- JB., Emerging Pro Athlete

Pension Fund

Denise has an unusual ability to help a decision maker understand the real, underlying drivers for the decisions they make. Her approach is highly unique and very powerful.

- Fortune 500 Pension Fund, Senior Portfolio Manager

David K

Denise has a unique way of working with high-achievers to help them go further and past what may be blocking them. She is an expert at helping to navigate the complex situations in our business and helps with my decision-making process in high stress situations. 

- CAA Pro-Sports Agent

Andy P

We brought in Denise Shull and The ReThink Group to expand our performance program and to obtain the benefits of a top-flight mental game for all our pit crews. Feedback from our athletes has been very positive and we've already experienced benefits in the races at Talladega and Dover. We look forward to continuing to learn from ReThink and to achieve the competitive advantages we anticipate will occur from our work together.

- Andy P., Director, Human Performance, Hendrick Motorsports


Even the smartest people in the room are listening when Denise is sharing insights on how we overcome our behavioral biases. Denise tells you how to hire the X-factor of portfolio management, how PMs come back from a losing streak and how to help COO's create a coaching environment, all in 60 mins.

- Avijit Choudhury, APAC Head of Capital & Consulting Services, UBS


Denise is the Yoda of the performance coaching world - spend time in deep interaction with her and the crevices are no longer frightening, the daunting peaks gradually become scalable and a sense of enlightenment appears. I have found Denise’s approach to self-regulation and sharpened awareness to be a game-changer. There is no substitute for Denise’s coaching in terms of razor-sharp uniqueness and insightfulness.

- AK, Family Office Investor, Former London Hedge Fund Manager

Sarna SL Broadway

Denise has been instrumental in helping me to reframe my anger. Through working with her I have learned how to harness the energy contained in feeling angry. I can identify the root of the emotion in a way that allows me to face it and decide whether or not it is productive to act on it. In a job where I am in a high-pressured leadership position, this tool has become invaluable. I have more positive energy to put toward good decision making and have improved my clarity and confidence.

- SL, Broadway Director

Tommy Thornton

I have known Denise for years and have to say there is nobody better at understanding the human element when it comes to trading.

- Tommy Thornton, Hedge Fund Telemetry
