Chris Jack
Head of Customer Experience at QTAC


Andrew Prosser
Principal Consultant, Artis Group

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?

Paul Gabrielides
Principal Consultant, Independent Communications Consultants

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
Managing Director, Quantum Exchange

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.

Gill's knowledge of Microsoft Dynamics was only surpassed by Edward's ability to deduce, discover and calculate his way through concepts that they were unsure about. Their capacity to continue to assist me in my pursuit to explore possibilities is a testament to their perseverance and tenacity in ensuring our company flourishes.

I have no hesitation at all in acting as a reference for Opsis and will happily accept calls from their potential clients.

ICT/Program/Project Management Consultant, NSW Dept of Finance - Lands & Property Information

Opsis were brought into LPI to help the organisation transition from multiple CRMs to a single integrated Microsoft Dynamics CRM solution. They worked with technical and business staff to progress from high-level business requirements to develop and implement a detailed technical specification. This included liaison with subject matter experts, implementing and configuring out-of-the-box CRM, then training end-users. Opsis were extremely professional throughout the process, demonstrating an excellent grasp of both business and technical issues. Their work was detailed and accurate, and they were proactive in communicating the changes inevitable in such a large project to all stakeholders.

I would recommend Gill, Edward and the Opsis team to anyone who needs assistance with Microsoft Dynamics CRM, and am happy to have a phone conversation if further details are required.

Financial Controller, McKenzie Partners

The difference Opsis have made to our CRM and our business is amazing. One thing I love is the new reports they designed to handle our media sales.  We thought it couldn't be automated because we have such a varied and complex list of products, but we were wrong!

Repeat orders are easy too - our BDMs just copy the previous order with a couple of clicks. So much easier for sales, plus it saves me a day or two every week entering sales into MYOB.  That's time I can now spend doing my real job - thanks Gill and the Opsis team!

Opsis has helped us to better understand campaigns and the sales process in CRM and we can now see where productivity can be improved across the business.

The training and support we so desperately needed have been great for my team who have really appreciated Gill's advice as have I.

Wal Williams
Sales Manager, Ico

Gill's knowledge of the Microsoft CRM product was excellent and her recommendations allowed us to come up with practical ways of adapting the product to meet our unique requirements. We are now able to complete client proposals in an average of 30-40 minutes, a process that used to take anywhere up to 2 hours previously.

CEO, Applied Training Solutions (talking about the Greenhouse project)

The employee satisfaction has increased because the team are not creating reports as a separate activity - they just do their jobs and reports happen in the background.  Lost customers are a thing of the past.

She is very keen to deliver what I like to call the "perfect" training experience, which results in extremely satisfied customers. If you need someone to lead CRM change realization, it's Gill.

Gill did an outstanding job when reviewing a very difficult test.  Her feedback was well thought out and clear to understand. She is truly an asset and I do hope I get to work with her again.

HNW Financial Planning Gosford is a client of Gill Walker and OpsisRobert Cumming
Business Owner, HNW Financial Planning - Gosford

Financial Planning requires an understanding of the complex interaction of a number of persons and legal entities who or which might have different types of investments, debts, insurances and estate planning. Liaising with clients requires individual consideration and access to a large pool of data.

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

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.

Codruta Guler
Project Consultant, Aspira

Thank you Gill Walker for the amazing PL-200 technical training! You are an amazing trainer! Was a very nice experience!

Allan Smith
Business Development Manager, Ezi Payment Solutions - Queensland

It gives me great pleasure to recommend you simply because, in today's world, 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, on behalf of Opsis, has shown professionalism and integrity of the highest level and that neither she nor Opsis, whilst conscious of profitability, as one must be, are not driven solely by the holy dollar and place client satisfaction above purely monetary reward.

David Nomchong
Managing Director, Global Qi Alliance (Marketing Company) - Frenchs Forest

Gill walked me through the CRM process, she made the complex simple to understand and gave me the tools to make important strategic decisions. I found her diligent, enthusiastic and easy to communicate with. Gill is able to assess the issues quickly and works well with staff.

Jack Fraenkel
Managing Director, Motivatories

Gill "Walks on Water" when it comes to CRM and I know that she will ask you to define what you really mean and want by CRM. Is it simply a contact management tool that you can store some history on, or do you need other sophistications such as pipeline, programmed contacts, stored templates etc? Anyway, she will beat you into submission and you will come off the canvas with a much clearer idea of what will suit your needs. I am happy to recommend Gill and have many times, always with good results.
