Your services don’t sell themselves, but clients still need your help.

You’ve spent years developing your agency’s expertise. You know how to deliver them. But selling and marketing your services is a different skill altogether. What you need are the right systems to attract and win the clients who should be working with you right now.

Any of this sound familiar?

You’re getting ghosted.

You speak to prospects who seem to love you, then they fall off the face of the Earth.

Deals are unpredictable.

You know how to run client projects, but your sales process sometimes runs off the rails.

The good ones get away.

You spend hours writing proposals only to lose deals with prospects who absolutely should become your clients.

Get the sales and marketing skills to grow your business.

Hi, I’m Liston, creator and founder of Serve Don’t Sell. I started my career surrounded by entrepreneurs and experts, but they didn’t know how to sell and market their expertise. 

I went on to open my own digital marketing agency and found that I could still win clients even though we weren’t the absolute best at what we did. The difference? I learned how to sell and market my expertise, and now I’d like to help you do the same.

I’m on a mission to help experts become world-class communicators so they can sell their expertise as well as they deliver it.

The Path to Growing Your Agency

Here’s how my signature Systematic Selling Program works:

1. Apply For a Consult

Schedule a quick intro call to discuss your goals and some immediate actions you can take to improve your client acquisition program.

2. Set Performance Goals

If we decide to work together, the first step is to set goals for your business growth, and identify the top priorities to get started with.

3. Monitor Growth

We’ll monitor your business growth, celebrate wins, and adjust priorities to keep the momentum moving forward.

Liston Witherill and the Serve Don’t Sell method is exceptional. It’s a wealth of information you won’t find anywhere else.

Our understanding of the sales process, our tactics, and the ways in which we seek to serve our customers has changed entirely as a result of Liston and his methodology.

The Serve Don’t Sell Promise

Rooted In Science

The methods and recommendations always consider experience, real-world feedback, and academic and business research.

Kindness Counts

Sales and marketing is about communicating effectively so people can make informed decisions, not be manipulated.

Tech Savvy

Yes, this is all about relationships, but technology can help with that. Wherever tech can help, we’ll suggest you use it, and how.

We’re Process Driven

You don’t have to be oozing with charisma to grow your biz, you just need a repeatable, proven process to follow and tweak.
