“Utilizing Shannon Roddy, Amazon Specialist, made the different between success and failure with our Amazon launch. Navigating the Amazon world with a mature brand required a significant amount of clean up and optimization and we couldn’t be happier with the service and intelligence that Shannon has provided to our brand in such a short amount of time. The results have been outstanding!”

Dale Malone, Klik Belts

“Working with Shannon is like having a good friend beside you helping to navigate the world of online marketplaces. Shannon’s expertise in getting products posted, discovered, cross-promoted and selling on Amazon helped my bedtime toy brand, Starshine Watchdogs, achieve fast-selling, 5-Star, zero-return status on Amazon! You rock Shannon – Thank You!”

Geoff Roesch, Starshine Watchdogs

“Shannon is really easy to follow and understand. He goes at a steady pace – not too fast or too slow. He really understands how to make solid listings on Amazon and how to optimize them for the most impact and sales. I highly recommend his course!”

Cynthia, Rengöra

“I tell anyone if they have anything to do with selling or even are considering selling on Amazon, they need to go through this course FIRST. This is the type of information that can save you TIME and MONEY.”


“As an agency owner, I’ve worked with Shannon for over a month. I personally went through his training courses and pulled out numerous practical pieces of advice that great accelerated my understanding of the Amazon marketplace from both a paid and organic perspective. Shortly after completing the courses, I utilized Shannon’s 1:1 coaching services to drive bigger impacts for some of my existing clients and also utilized his services to help me pitch new business. Shannon is an invaluable extension of my core team and always over-delivers on his engagements.”

Damien Cabral, Partner and Co-Founder - TribalVision

Matthew Vick, Senior Marketing Manager - TribalVision

“Shannon is a true expert in the leading practices on Amazon Seller Central. His insights into the countless nuances that go into being a successful Amazon Seller makes him an invaluable resource that every brand owner should utilize.”

Matthew Capalbo, Allstar Products Group

“I am so glad that I reached out to Shannon for help!  I needed to make some changes to my Amazon business. After an exhaustive search through Amazon’s policies, as well as multiple Google searches, I was completely confused as to how to proceed.  I reached out to Shannon, and he got right back to me saying he would absolutely be able to help. He called and walked me through everything that needed to be done. And in just 15 minutes, I was all set!  I’m kicking myself for wasting so much time trying to figure it out on my own when I could have saved myself a lot of stress and just contacted Shannon.  But I’ve learned my lesson now. Moving forward, I will contact Shannon first!  And I highly recommend him for anyone who needs help with their Amazon business!” Thanks for taking the time to help me out this morning!”


“Shannon is by far the most knowledgeable person I know when it comes to Amazon. I’ve worked with a number of Amazon-specific agencies and none of them come to the table with the breadth of knowledge and understanding that Shannon does when it comes to Amazon. In fact, since starting to work with him in January of this year we have seen our monthly Amazon sales rise 400%+. Highly recommend that any and all marketers and business executives hear what Shannon has to say!”

Denise Day, Director of Marketing at Good Day Chocolate Supplements

“I am in marketing and with launching my first product on Amazon, I am pleasantly surprised to have learned so much in just the beginner course. There is a lot of thoughtful detail and strategic thinking that went into the content of this course. I also found the extra resource links useful!”

Jayme Derkson, My Starry Chart

“Shannon is very specific when explaining to you what he is going over. He wants to assure you understand before moving forward. Shannon is very knowledgeable of his line of work.  He doesn’t tell you something if he doesn’t know it. He is very honest and wants you to succeed.”

Denise Odermatt, Almased

“I’ve been selling online since 2003. I can tell you with all sincerity that working with Shannon is such a breath of fresh air. He’s trustworthy, super knowledgeable and a pleasure to work with.

Not only are his courses top-notch, but his consulting is more than worth the investment. Bottom line: If your business is looking to “up” its Amazon game, look no further. You’ve come to the right place.”

Jim Labadie, PhysioTru

“You are doing a great job and I’m so happy to have found you. I have been searching for 6 years to find someone who understands these amazing products and it has been very frustrating!!! Many, many thanks!”

Margaret Sinclair

Jeanie Mehran, Melon Rind Games

“All the other vendors are selling variations of “get rich quick” with Amazon and how to find the next iPhone cable to sell. This is the course for the serious seller that wants to understand Amazon and grow their business.”

George Clark, Pure Country Weavers

“I worked as an instructional designer for 5 years and I have to compliment you on your courses. The tutorials were very organized and well constructed. I was engaged and never distracted or lost as you did a great job of explaining every step.”

“Highly Recommend! We’ve been selling on Amazon for years, but the information and resources here in Shannon’s course has helped me and my team deepen and grow our understanding of the Amazon marketplace with all its complexities and ever-changing policies. We’ve greatly benefited from this course and appreciate Shannon’s ability to easily layout information into actionable pieces while providing depth and valuable content.”

Rebecca Avila

“When we started to launch NAPGEAR we really had no idea of what we needed to do to be successful on Amazon. Our sleep aid products are in a highly competitive area and every bit counts to make a difference. Shannon’s course on launching new products on Amazon removed any uncertainties we had. It provides a great overview of the steps that needed to be taken and goes into detail with all of them so that an Amazon newcomer can be as successful as possible with their listing. With this course you will create the best listing you can. I encouraged my team to review the course and recommend it to anyone wanting to be successful in launching their products”

Tammo Heeren, NAPGEAR

He has tremendous knowledge about the ins and outs of Amazon and is great to work with.”
