      Ken Phillips's Review Sourced from Google

      I have worked with Helixstorm since before it was Helixstorm and the entire team has never failed to go "above and beyond" before, during and most importantly, after every engagement. Aaron and Eric are the best of the best and they'll work tirelessly to make sure your project is delivered on-time, on-budget and with all deliverables completely functional every time. Few businesses share their integrity, focus and innovative approach to technology. They're partners in every sense of the word and they never fail to deliver outstanding results. You'll know lady luck has smiled on you if you get the opportinity to work with these guys and they will likely be the last consultants you'll need to seek out...:)
