Training & Education
Thank you Gill Walker for the amazing PL-200 technical training! Thank you so much for everything! You are an amazing trainer! It was a very nice experience!
Codruta Guler, Project Consultant at Aspira – After PL-200 Training, May 2022

Thank you Gill for these days. I agree with Codruta! :)
Mikael Arvidsson
Thank you very much for the lessons, I learned a lot of new stuff concerning model driven applications and Dataverse, since we work mainly with SharePoint as a back-end. But I have a feeling that is going to change in the near future.
Niels Asselman, M365 Consultant – CTG Belgium

In the Sydney market, Gill is "Ms CRM". There is, quite frankly, no-one else in the market with as much experience and knowledge of the Dynamics CRM/CE ecosystem as Gill. I've worked with Gill many times over the years and would do so again without hesitation.
An accomplished speaker, excellent trainer, and possessing deep domain knowledge of the challenges faced when implementing sales and marketing platforms ensure you get immense value from just a 30 minute conversation. Spending a day with Gill will change how you approach software project delivery forever.
If you are considering Dynamics CRM/CE and have yet to engage Gill, then you are leaving a tonne of opportunities on the table. What are you waiting for?

CRM Implementation & Strategy
I count Gill as a friend, having spent years fighting with her while she was consulting on a CRM implementation for my company (Quantum Exchange) too long ago to remember.
All jokes aside, I can not recommend Gill highly enough to do her justice. What I love about Gill is that she tells it as it is. Her qualifications are second to none. Gill is the one person that you want on your side when you are establishing a CRM. And if you haven’t engaged her in the first instance, Gill is the one person to engage if you need your CRM to function as you had initially hoped.
Gill and her team of consultants have access to the skills you require to get you through the basic Microsoft 365 and Teams implementation and synchronisation.
Paul Gabrielides, Principal Consultant – Independent Communications Consultants
As Managing Director of Quantum Exchange, I take great pleasure in recommending the services of Opsis, Gill Walker and Edward Birch.
Their skills in implementing Microsoft Dynamics into Quantum Exchange were stretched to the limit. Not only did they have to deal with the existing databases of two different companies each of which had been operating for over twenty years, but they also had to endure the egos of the five directors.
As a result of their efforts, I was able to merge two companies and two groups of people into one unified team and managed to do so in a tight time schedule.
I have no hesitation at all in acting as a reference for Opsis.
Paul Gabrielides, Managing Director – Quantum Exchange
Opsis were brought into LPI to help the organisation transition from multiple CRMs to a single integrated Microsoft Dynamics CRM solution.
Colin Hickling – NSW Dept of Finance, Lands & Property Information

Gill Walker helped HNW Planning in scoping our project and in helping our own development staff to get up and started. Gill remains a reliable and knowledgeable reference for us.

CRM Impact & Business Results
The difference Opsis have made to our CRM and our business is amazing. Repeat orders are easy — our BDMs just copy the previous order with a couple of clicks.

Client proposals now take 30–40 minutes instead of up to two hours.

The employee satisfaction has increased because reports happen automatically in the background. Lost customers are a thing of the past.

Integrity & Trust
It is very rare indeed to find a company whose staff are prepared to go that extra mile for their customers as you have done for us on a number of occasions.
Gill has shown professionalism and integrity of the highest level and places client satisfaction above purely monetary reward.
Allan Smith – Ezi Payment Solutions

Gill walked me through the CRM process and made the complex simple to understand. She gave me the tools to make important strategic decisions.

Gill did an outstanding job reviewing a very difficult test. Her feedback was well thought out and clear.

Gill walks on water when it comes to CRM. She will ask you to define what you really mean and want by CRM and you will come away with a much clearer idea of what will suit your needs.
