Who We Are

Letter From The President

Integrated Back Office Enterprise is the 'go to' for industry professionals. I started this team because constraints I ran into became so frustrating. When a project or work was outsourced, the people performing the requested work had no idea what they were doing. I don’t call that customer service. My frustrations grew so I flew. Yes. I left my then employer of 10 years. My husband and I sold almost everything we owned and moved to Costa Rica. Through my industry connections I consulted on Oil and Gas projects and Tax Planning services during the year we were immersing ourselves into the Tico culture. I flew back to the United States for national COPAS meetings. I'm passionate about the Oil and Gas Industry and helping business owner's profit and grow. Returning to the United States, I consulted with a few companies and found the same frustrations I've encountered throughout my professional career. The questions came: "why can’t we find consultants that know what they are doing", "why are we paying for out-sourcing and having to explain how things work or do the work ourselves", "do you have others we can contact that know [fill in the blank]". The big light bulb came on when a private equity upstream company was in a transition and had to let their contractors go. The principals were concerned because they cared about these contractors. Discussion began. The respect and trust from this client overwhelmed me. The client wanted to have access to knowledgeable people when they needed them and from a source they trusted. This led me to reach out and contact people in my network. This was not just a start-up issue; I was hearing the same story over and over. I was given a chance when I started my career and wanted to pay-it-forward.

I believe in giving people the chance to thrive. If you want to learn, I’ll teach you. If you don’t know something, ask. If I don’t know, I’ll tell you, and can probably find someone that does know. We can learn together. We aren’t the professional contractors that perform the requested functions and leave; we see our clients as partners in a journey to alleviating stress and worry while achieving their goals to ensure continued success.
