We have been utilizing Ontech for almost 3 years now. They have been great with response time to service calls and are very knowledgeable with HIPAA and Security which is a very important part of our business. They stay on top of current requirements and recommend appropriate software/hardware when needed/required.

Our company has been with Ontech Systems, Inc. for many years. Scott Schepp is our Tech. No matter what the issue, he is there for us, and extremely helpful. He explains things in a way a "non techy" person is able to understand. Scott goes out of his way to ensure that we are taken care of immediately and follows up on all of our questions, no matter how small, in a professional manner. Highly recommend!

My company has been with Ontech Systems, Inc. since their start. No matter the issue, big or small, their staff are quick to respond and get things resolved. Their team is extremely helpful when it comes to staying current in the ever-changing world of IT, and they are an instrumental part of our preparations for the future. Highly recommend!

Ontech does many things right. From the initial assessment of the IT needs of my office they have worked to anticipate potential problems, offer different solutions, and make sound technical and financial recommendations that best suit my specific needs. Their willingness and ability to educate me on the different options or concerns that have popped-up is greatly appreciated! I know that I am not their only client, yet they always make me feel like the only person on the schedule. In 2017, they started an online portal to view and pay the invoices. It is a wonderful way to keep on top of my IT expenses. Mike, Mark, Jackie, Katelyn, Dan and the other members of the tech support team are wonderful!

I have had Ontech as our IT partner for many years now and continued to be impressed with the quality of service they provide. Their secret sauce is their team members are both highly qualified IT professionals as well as having great people skills. They are a great partner that helps us understand and implement what we need from an IT perspective to grow. I have referred them to other business owners / operators and they too have had great things to say about Ontech.

Ontech Systems meets the needs of our small professional service firm. We have used their IT services for several years now and feel that with today's scammers such as server, e-mail and internet intruders getting more clever with attacks each day that we are on solid ground. Our technician Dan is great to work with on simple and the most complex IT matters that we experience. We are always confident with Ontech as our go to IT firm.

The service has been nothing short of great! Ontech goes out of there way to ensure that we are taken care of immediately and follows up to all of our questions, no matter how small, in a professional manner. Highly recommend!

My full time employer came across OnTech from a cold call from Jackie. While talking to her, OnTech had better rates than the company we were currently using for outside tech support (I'm being nice and not naming the company). As it was, the outside tech support company we were using at the time we were becoming unimpressed with, so I talked with management into giving OnTech a chance.Once OnTech came in as our outside tech support, we've been nothing but impressed! Dealing with Keegan, John, and Dan (as well as a few others, but these 3 have been our main contacts) has always met or exceeded the expectations of ours. The team actually listens to what we have to say for what we are looking for and will come back with one or more solutions at all times.In the end, I highly recommend OnTech to anyone looking for a team to help give you resolutions with your technology needs as well as support!

I have used Ontech System for my business and personal computer needs for years. I came to them in a situation where I had lost my current IT company and needed to immediately have them assess and recommend what I needed to protect and run my business. They were amazing! They are professional, prompt, budget conscious, and generally a great company and people to work with. I have recommended them to many of my professional and personal contacts. I cannot say enough about who they are and what they deliver.

For over 4 years, Ontech Systems has provided Public Allies with a consistently high level of support and customer service that has allowed us to have full confidence and trust in them. We've worked with other IT companies, but none of them come close to the service provided by Ontech.

We’ve been outsourcing Ontech for a couple of years now. Their staff is knowledgeable, responsive, and proactive. We utilize them for onsite IT services, monthly managed services, and network projects. They do their homework on our various software systems to make sure our network always meets system requirements. Dan is our main man at Ontech. He has the ability to explain to me the IT side of things in normal, understandable words. IT issues can bring your business to a halt. Ontech keeps it going!

Our infrastructure was aging and was in need of a refresh. We spoke to several potential vendors finding most of them trying to force us into a standard configuration. Instead, OnTech listened to our needs making several recommendations along the way. We were able to build a scope of work in which we were both confident. And then, they delivered the project. Of course, there were a few challenges along the way, mainly due to our lack of valid documentation, but the OnTech team was accountable to the end result. The project was concluded on time and on budget. We continue to use their on-going support today.

We hired OnTech a year ago, and are grateful we did! Prior to, we heard complaining from team members regarding various tech elements. No more! Our company invested in the equipment/programs they suggested for OUR company and OUR size of staff. They were spot on! No more complaints about slow computers, programs freezing up, or being tied to the phone. OnTech has given us freedom, flexibility and security in our day to day work life. In fact, I’m not sure how we functioned without them!Have a problem? Need something urgent fixed/looked into? ONTECH! Today is a GREAT example of their efforts. I called in with a problem that had a team member shut down. Shortly after, our IT Consultant, Dan Dineen, called to help me and SOLVED the issue. Dan is endlessly patient; his knowledge is amazing and he’s always going above and beyond. That’s OnTech as a whole! I’m impressed every time I need to call in for help.If you are looking for help with any of your IT needs, look no further! Call them TODAY!
