K.Y., CHAIRMAN OF OIL & GAS COMPANY (USA)
“You couldn’t possibly be working with a more diligent and personable team of lawyers, most especially, the Managing Partner, William Kirtley. Aceris is about the best law firm in services and cost I’ve ever dealt with. Every member of the Aceris team is truly exceptional and dynamic, a quality that is truly personified in the person of the managing partner, William Kirtley. As earlier stated, Aceris is quite an exceptional team of lawyers, the reason I rank the firm very high on the list of law firms my company has worked with in our over 24 years in business.”

L.A.M.C., SECRETARY OF STATE, MINISTRY OF ENERGY AND WATER (ANGOLA)
“I would like to express my heartfelt gratitude to the Aceris team on behalf of the Angolan Government, specifically to the Managing Partner William Kirtley and his Associate Nina Jankovic. Their intelligence, passion, dedication and professionalism are beyond what any client would expect. They were well organized and worked closely with our technical personnel to prepare the case in a thorough manner, always ensuring that our concerns and suggestions were properly addressed. I am blown away by how quickly they could grasp the very technical engineering aspects of the case.”

F.P., GENERAL COUNSEL OF PUBLICLY-LISTED COMPANY IN THE PETROCHEMICAL INDUSTRY (MALAYSIA)
“This [arbitration] result is by far beyond any expectations and I still can’t believe it happened. Excellent news to all of us. Unbelievable.”

C.B., GENERAL COUNSEL OF BLOCKCHAIN-RELATED TECHNOLOGY FIRM (USA)
“Aceris Law LLC’s Arbitration Group, led by William Kirtley, shows exceptional judgment at all levels. They are client-oriented and have effectively represented my organization in a prompt and timely manner across several time zones. My Team has been kept fully informed and has been able to rely on William Kirtley’s judgment in making key decisions during the course of the arbitration.”

R.K., C.O.O OF ENGINEERING, PROCUREMENT & CONSTRUCTION COMPANY (OMAN)
“The team was very systematic, professional and thorough in their approach. Once the initial engagement agreement was done, they never bothered about the man hours spent on the job. Their objective was to present the case with a hundred percent winnable angle. Their speed in grasping indicates their previous exposure. Overall we found them very professional with a friendly attitude yet unhesitating in demanding required data relentlessly. Mr. William Kirtley is a strategic thinker with excellent memory and recall ability enmeshing various previous judgments across the globe into the present case and Ms. Nina Jankovic is a methodical researcher with a very sharp intellect, cutting through unnecessary information with excellent drafting ability to present the case succinctly.”

G.M., CEO OF UPECO TRADING A.G. (SWITZERLAND)
“I highly recommend [William Kirtley and Aceris Law] for international arbitration legal counsel. He is an excellent practitioner and a top-notch professional. He is highly reliable and will never give up on a client’s case. He is very experienced as legal counsel and a very good person as well. He can see all details which could be decisive in the arbitration. His goal is to bring meritorious cases to victory and he does the best of it. I recommend him as a professional and a person who never abandons a case halfway, no matter how hard a case can be.”

S.A.U., MANAGING DIRECTOR OF OIL & GAS COMPANY (OMAN & USA)
“We find them very methodical. Quick in grasping as they have varied exposure. They specialise in arbitration. They understand the subtle nuances. We find their approach very friendly yet professional, timely, easily approachable, very responsive. Honestly, the entire team were supportive with professional approach. Specifically, Mr. William Kirtley: He has a knack of anticipating the possible questions by the arbitrators, possible defences by the respondents. His weakness is adorable i.e. his charges are reasonable.”

A.A., VICE PRESIDENT OF CONSTRUCTION COMPANY (SAUDI ARABIA)
“[The] Aceris team is very good, hard working, competent and cost efficient with comparison to other law firms that works in the same field. They have a very high capacity to perform legal research and their lawyers are very well trained in the arbitration field. William Kirtley is the head of the team and the person I know for the longest time, Nina Jankovic and Zuzana Vysudilova are the two main associates that handle all the firm cases. In general, William, Nina, and Zuzana are very meticulous, which I consider as an important skill in this field of work, they also have a very good background in different laws and jurisdictions (especially Saudi Law which is important for me as I work in a Saudi Company).”

“Aceris’ lawyers are friendly and professional, their legal drafting is excellent, their legal fees were reasonable, their strategy was successful and we highly recommend Aceris Law for international disputes that are capable of resolution through arbitration, which is their specialty. Although they are based in Europe, the dispute was in California and our company is located in the Philippines, the time zones posed no practical constraints since they are well-equipped with the latest technology and available around the clock by videoconference.”
