About Us

We are trained and experienced business partners, M&A advisors, and troubleshooters. We function as trusted advisors, subject-matter experts, or an extension of your team.

We serve organizations and departments, executive leaders and managers, in any role where we can best add value to your organization, and we get things done.

Proton Consulting Group is an effective business consulting partner.

Our passion is to solve business problems

Solving business challenges is why come to work every day. Some professionals re-engineer corporations. Others advise on the purchase, sale, or financing of businesses. Some redesign processes. Or, recruit or develop resources. We get to do it all for our clients. 

Your company has already achieved success. Today, to develop further, it needs assistance from experienced problem solvers unfettered by current challenges or politics. That’s us.

We love change

Change is what will move your company, your department, your team from where it is today to where it must be tomorrow to lead the space.

We think outside the box

We don’t allow ourselves to be limited by the current state of a challenge, or a project, or the business. We challenge answers and challenge the answers to those challenges. Only by getting to the true underlying reason behind a process, can we provide a more efficient alternative solution. And, we do.

Our solutions are practical

We only provide opinions that can be deployed immediately, not ones that would require a change before the changes, not ones that look good on screen but are not practical. And, we know a thing or two about deployment logistics.

Always learning

How could we not? We deploy training solutions. But, also we learn everyday from each other, from our peers, from all our engagements, so our clients can benefit from it. So, your company can benefit.

Integrity is key

Integrity is core to all we do. To who we are. We are not for everyone and not everyone is for us, but, if we work together, we will be the partners that we would want to have.

We will provide our best opinion on all engagements and use best practices for all deployments.

We are committed to excellence

We help organizations achieve operational excellence. We help organizations that have achieved operational excellence to leverage it.

And, our engagements are successful only when you are satisfied, only when you are successful, only when your company’s performance has improved.

Nothing short of excellence.
