Sales Development Doesn't Too often, training programs create short-term excitement. Sales teams attend a workshop, learn a few techniques, and returns to old habits within weeks. The Sales Development Series is different. This comprehensive learning, reinforcement, and accountability system enables sales professionals to continuously improve their skills while producing measurable results.  We develop long-term partnerships because building an elite sales team isn't an event. It's a process. [Schedule a Discovery Call](https://meetings.hubspot.com/john-nelson7/discovery-call) ## The Challenges If you lead a team, you already know the pattern:  - As a leader or owner, you're closing all the deals and it's not changing. - A rep has a great quarter, then a quiet one and nobody can explain the inconsistency. - Stalls moving opportunities through pipeline stages. - Opportunities are not fully qualified, or disqualified, resulting in inaccurate forecasts. - Sellers are giving away "unpaid consulting" and too many discounts. - Getting ghosted because next steps are not established. These aren't talent problems. It's a lack of a system problem. The Sales Development Series is how you fix it for predictable growth. ![Sandler Selling Sytem Wheel](https://marinsalesadvisory.sandler.com/hs-fs/hubfs/Sandler%20Selling%20Sytem%20Wheel.png?width=350&height=350&name=Sandler%20Selling%20Sytem%20Wheel.png "Sandler Selling Sytem Wheel") Average Benchmark Results from Sandler Training: \- 27% Higher Win Rates \- 18%  Increase in Deal Size \- 50% More Reps Hit Quota \- 33% Faster ramp for new reps An Integrated System, Not Just a Single Class The Sales Development Series is a continuous development path, not a one-off workshop. It starts with Essentials and carries straight into Mastery where foundational principles are strengthened with advanced skills and techniques.  Start with Essentials 10-Weekly Virtual Sessions covering the core 7-step Sandler Selling System where sellers will learn to: - Prospect with confidence - Conduct effective discovery conversations - Uncover buyer pain - Qualify opportunities - Discuss budgets comfortably - Gain commitment - Handle objections - Close naturally without pressure Essentials creates a common language and repeatable sales process across your team. Mastery: From Knowing It, To Owning It Elite salespeople aren't created in ten weeks. Mastery layers in advanced tactics, deeper one-on-one coaching, and tech tools like AI-powered roleplay. It's where good salespeople become exceptional. - Advanced techniques and objection-handling under real conditions - Ongoing coaching and quarterly leadership reviews - AI roleplay and reinforcement tools to improve messaging - Executive selling and complex opportunity strategy Why it's built this way: Behavior change that lasts requires reinforcement. Ten weeks is enough to learn a new process. It's not enough to make it permanent. Essentials teaches the system; Mastery is what makes it stick. Yes!

Improving your sales team's performance through the adoption of the Sandler Sales Process. Sales leaders are actively involved, building their own skills so they can consistently coach, support, and reinforce their teams. As you grow, so does the partnership. We help you extend the Sandler Methodology across every customer-facing team, not just sales, so the whole organization runs on the same process, speaks the same language with clients, and builds relationships that last. The result: efficiency first, then effectiveness, then a client-focused culture built to scale. *"Through this course I've learned to show up with confidence and clarity, balancing assertiveness with respect for myself and others." ~* Precious Kofi [Book a Strategy Call](https://meetings.hubspot.com/john-nelson7/discovery-call) ![John Nelson 2](https://marinsalesadvisory.sandler.com/hs-fs/hubfs/John%20Nelson%202.png?width=200&height=200&name=John%20Nelson%202.png "John Nelson 2") John Nelson Principal, Instructor, & Coach At Sandler by Marin Sales Advisory, I help companies grow by developing high-performing sales teams and strong sales leadership.
