The Professional Land Surveyors of Ohio was incorporated in 1972 and today remains one of the largest and most active statewide land surveying associations in the country. PLSO's more than 1,000 members include professional surveyors, surveyor technicians, interns, and others who work in the industry; students; and companies engaged in supplying services and equipment to the surveying profession.
PLSO Vision Statement
PLSO strives to advance, support, improve, and enhance the profession, its members, and the practice of surveying by:
Holding the safety and welfare of the public above all other considerations, placing service above profit, and the honor of the profession before personal advantage.
Protecting the rights of those persons practicing the profession through collaboration with organizations, the board of registration and the legislature.
Conducting our business in an ethical, efficient, cost-effective, and professional manner.
Providing timely information and pertinent educational opportunities to our members.
The Surveyors Pledge
To give the utmost of performance.
To participate in none but honest enterprise.
To live and work according to the laws of man and the highest professional conduct.
To place service before profit, the honor and standing of the profession before personal advantage, and the public welfare above all other considerations.
In humility and with the need for divine guidance, I make the pledge.
