Mariano and his team tested each process, reviewed them and revised the system to meet our specific sales needs,” explained Charles Betances. “He and his team are very professional, and I am very confident with the job they did. We have some young employees with high intelligence and energy, but they need a platform to follow, and Salesforce CRM allows us to monitor their progress.

We knew Doble Group had extensive experience in the Caribbean, and they were a good fit for us… Once we put together the skill set for which we needed to recruit for our sales department, Doble Group advised us to implement Salesforce CRM to help control the activities and sales cycle for our corporate sales.

Without this training Salesforce could never be used to its full advantage and feel confident that success is inevitable! Mariano is a giant in terms of his ability to translate Salesforce to people who may not want to adopt a new way of doing things. I am totally sold!

Since bringing in Doble Group to optimize our use of Salesforce CRM, we have noticed increased productivity from our salespeople, and information is flowing better throughout the sales team, resulting in better communication.

The Doble Group team was very informative about what could bring to the table and the increased functionality it offered. It has increased the productivity of our sales team by allowing them to step up their efforts through the use of Salesforce. We like the usability and intuitiveness of the solution.

"Its a great service. The project planning, the consultant effort in order to get all the client's needs fulfilled and the time invested to listen (to our needs) was fantastic. Our overall experience was excellent.”

Craig Binns, Salesforce Project DirectorDigicel Group
"Mariano and The Doble Group are very professional, they have constant meetings during the set up and implementation stages to keep everyone informed of the projects timelines. The team at Doble Group is always willing to assist and give recommendation where necessary and most importantly, they delivered within the agreed timelines set out to them. I would highly recommend Doble Group.”
Patricia RileyProductive Business Solutions

In 2010, PBS set out to standardize its sales processes across 13 countries in the Caribbean and Central American region. To achieve this mission, we required the expertise of a company that could chart the course and also help us execute a multi-national sales transformation program. Doble Group turned out to be the ideal consulting firm!

I've observed several hundred senior managers and their teams at close hand over a 20 year period and Mariano sticks in my mind as one of the very best. He was able to clearly articulate his vision in a chaotic environment in a way that inspired and motivated his team to deliver their utmost, despite adversity.

In addition to significantly growing our sales, we've improved our sales meetings because we go into them with more data, more quickly to assess our clients. Our sales people like that, they can now use Salesforce as a tool to help them improve their sales interaction, and the technology helps them simplify that interaction.
Margaret ZarineCable & Wireless - Seychelles
Since we started working with Doble Group, our salespeople are using more data for their sales and are capturing more information, which is helping us close deals. They’re applying what they have learned through the training and are able to identify issues to better manage our customers. We've had so much success that we are looking at other training options that Doble Group can provide for ...
Hank PereaEl Catador
We wanted a CRM that would change and have a fundamental impact on the way we sell, and many American-designed systems don’t jive with the Latin American culture. Doble Group has cross-border experience, which reduced the culture gap, and we value the technology experience of Mariano J. Doble, CEO of Doble Group.
