— The Shull Method 

Performance and Risk Decision Consultants

Architecting our Clients' Optimal Results

We revitalize performers, inspire investors and reinvigorate management teams across finance, sport, arts, music and business.  

The Shull Method, our signature consulting and coaching framework, leverages the latest neuroscience and psychological research into perception and judgment.

Translating the findings into practical strategies, we resolve the stubborn mental challenges of conflicting goals, behavioral biases, resilience and motivation.   

A Client Writes, Summer 2022

Engage ReThink and its team of decision masterminds. WHY? Because they’ve figured it out. 

It wasn’t until I crossed paths with Denise’s work that things changed. My decision-making effectiveness increased. More importantly, my stress when faced with making consequential choices, amplified by a deadline, decreased. When the stress decreased there, it decreased in my home and at the office. 

Listen and read what she has to say. –RH, Jackson Hole, WY

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


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


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.

I recently watched Denise on Anthony Crudele’s show, and found her to be
cutting-edge and refreshing when compared to the stale/recycled
strategies in trading books and all over the Internet.

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

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.

I am still reading Market Mind Games but I just went through what I think was
the most mind-clearing moment I have experienced in my life.


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.
