Try calling the office of Aquinas at 713-914-8188 and if the receptionist answers, ask to leave a message, or the phone should direct you to an answering machine if everyone is out in the field or in other meetings. The company is not public, but contemplates filing soon. Presently the company office resides in a multi-story building on the sixth floor in Suite 600.
You might remember this is spring time and some folks have children graduating from schools out of town, or business meetings may be taking place in other locations, or officers may be looking at other lease opportunities. Then of course, once in a while you might expect them to take in a round of golf. So, don't be disturbed. And another thing to consider, I can't even reach my son unless I send a text message. Funny how things have changed in the last ten years. Seriously, do call and leave a message. A person in their office has said they would get back to you.
And I found that Aquinas has a website which might be helpful. Check aquinasenergy.com Cheers
