Our Customers

It's all about relationships, mutual respect, and listening. Many of our customers have worked with Robert since the early 90's when he began the business. The longevity of a realtionship says a quite a lot about the capabilities and integrity of a person and a company. Here are just a few of our clients, and we think they can say a whole lot more about the kind of work we do than anything else.


“We have been using Combined Technology as our IT department for 8 years now. We have been extremely impressed with their professionalism and service. They are always quick to respond, do a fantastic job and charge reasonable fees. We highly recommend their services.”

     Karen Miller, Hospital Manager, Woodland West Animal Hospital


“We’ve chosen Combined Technology for our IT needs because of their exceptional staff. They consistently respond to our calls for service promptly and with a great attitude. We trust them with our business!”

     Kathryn Neal, Stava Building Corporation


"Since 2012 we have used Robert Raskin and his staff at Combined Technology exclusively to handle all of our information technology needs – from setting up our network, recommending and installing computers and software, internet connections, email accounts – and everything in-between. We had one major office relocation in 2012 and added two additional offices in 2014 and 2015. This involved meeting the needs of 25 people in Tulsa and 18 employees in the field. Combined Technology coordinated with other vendors to make those transitions as seamless as possible and provided exemplary service to our company. They continue to meet our ongoing needs timely and with a level of service that just could not be better."   

   Larry Lee, President and CEO, RAM Energy LLC


“For the past 15 years, Combined Technology has provided excellent IT service. We depend on quality technical skills and trust CT recommendations in this area of our operations. It is a pleasure to work with a company that prioritizes building relationships and taking care of the customer’s needs.”

   Betty Lehman, Synagogue Administrator, Congregation B'nai Emunah


I love the response time from Combined Technology. The wonderful staff promptly comes to our assistance bringing their smiles and expertise. They have been helpful in making recommendations, while remaing mindful of the budget.
