Client Testimonials

I've known Jon Vague for three years and we have worked together on three different projects that required good contacts, good logistics skills, and very good interpersonal skills. The latter are particularly important when dealing with two very different cultures, in my case the US and Brazil. I can recommend Jon and his group as effective facilitators for any activity of this sort. He has good contacts in both the US and Brazil and his educational experience in both law and business, plus his comprehensive knowledge of the energy business, qualify him to handle sensitive cross border commercial energy negotiations.

Tulane University Energy Institute, New Orleans, Louisiana, USA


Jon Vague is simply remarkable. I'm amazed at his global connections and his ability to get things done. He's a consummate professional and has the experience to make any project succeed beyond expectations.

Mr. Terence O'Neill, Director of International Affairs, City of Houston, Texas, USA


Having worked in the oil and gas industry and private equity for many years, I know how important it is to get solid advice and build real relationships with partners from other countries. I highly recommend Jon Vague for his culturally-based understanding of both the U.S. and the Brazilian energy markets and the key players in each. He is efficient, ethical, and particularly helpful in integrating U.S. equipment and service companies with the Brazilian petroleum industry.

Stephen Hillard, CEO, Council Tree Investors, LLC., Austin, Texas, USA


I have known Jon Vague for over 10 years and have collaborated with Jon on various projects of an international nature, primarily focused on Brazil. Jon and I have jointly participated in presentations in Rio, Houston, Lafayette and New Orleans, and we continue to collaborate on presentations related to U.S.-Brazil energy transactions. Jon has fostered and maintained an extensive network of contacts in the energy and maritime sectors, and remains as much a business facilitator, as a business promoter, for U.S.-Brazil transactions. As a Brazilian-born American, Jon's contacts, English and Brazilian-Portuguese language skills and business orientation, allow him to consult and guide U.S. companies in Brazil, as well as in-bound work from Brazilian companies.

I have been in touch with Jon Vague for the almost 9 years in which he acted as our firm's representative in Houston. Besides being a competent, business-oriented attorney, Jon has a deep knowledge of the Brazilian market and culture, a somewhat rare quality much appreciated by clients. Also, his knowledge of the international oil & energy business makes him a valuable consultant for international companies doing business in Brazil and for the increasing number of Brazilian companies involved in the international market.

I had the opportunity to work with Jon Vague in several matters but I would like to mention one, where we were involved with a very complex issue regarding an entity interests in inbound investments in Brazil and different aspects of this investment (structure, judicial matters related to the investments, thoughts for the future, among others). Jon was able to provide to the entity focused and safe advice, grounded in professional experience and a broad perspective of Brazil.

Dr. Rodrigo Jacobina, Senior Partner, Doria, Jacobina, Rosado e Gondinho Law Firm, Rio de Janeiro, Brazil


I have known Jon Vague since his years as a student at the university [in 1986], where he completed several of my courses and was my academic advisee. Jon and I have been in touch since his graduation, and I have followed his academic and professional careers with great pride. Jon worked as an adjunct faculty member at the University of St. Thomas in Houston, and, reflecting his loyalty and commitment to those following in his footsteps, he has provided internships for several of our students. My ongoing association with Jon has been rewarding at both the personal and professional levels. His is a charm borne of sincerity and personal warmth as well as ability to communicate articulately his professional knowledge. I look forward to drawing on his ever-expanding knowledge of his field.
