Dr. Uriel Oko is the proprietor of Corrosion Services. With more than 30 years of experience in various facets of metallurgical, environmental and chemical engineering, he offers depth of knowledge and design capabilities. He graduated with bachelors and masters degrees from McGill University, Montreal, Canada and a Ph.D. in metallurgical engineering from the University of Missouri, Rolla.

Dr. Oko began his working experience as a student co-oping as a mill hand with Quemont Mining Corporation, Rouyn-Noranda in Northern Quebec. Upon graduation, he worked for the Canadian National Railways. During more than four years with Supreme Precision Castings, Montreal, he supervised the metallurgical investment castings foundry. He then worked for International Investment Castings in Belleville, Ontario before attending graduate school.

Upon graduating with a Ph.D., Dr. Oko returned to the mining industry, working for Falconbridge Nickel Mines Corporation in Sudbury, Ontario. He then joined the Acres Consulting Group and moved to the United States. He worked for Union Carbide Linde Division as a metallurgical engineer developing the PUROX system for converting domestic refuse into combustible gas. After four years with Union Carbide, he joined Cities Service Oil Company where he developed several processes for converting heavy oils and coal into gasoline. When Occidental Petroleum purchased Cities Service, Dr. Oko was engaged in problems related to deep well drilling and enhanced oil recovery.

Dr. Oko moved to Albany, New York in 1990. He obtained NACE qualifications as Senior Corrosion Technologist in 1996 and commenced a consulting practice. His projects include cathodic protection of tanks, concrete structures and water mains. His clients include industrial and commercial enterprises as well as numerous attorneys who call on his chemical engineering and metallurgical expertise.
