"Bob" Kaehler (born April 5, 1964, in San Mateo, California) is an American rower.

[1] Kaehler is a graduate of the Columbia University College of Physicians and Surgeons (1991) with an MS in Physical Therapy.

The exposure to these diverse training methods and philosophies helped shape Kaehler's singular perspective on conditioning and athletic performance.

[citation needed] Kaehler remains the most successful U.S. male heavyweight rower at the world championships level with his four world titles[citation needed], including a three-straight streak (1997–1999) with U.S. coach Mike Teti.

Along with three titles (San Diego Training Center U.S.A. -- Men's 8+) Kaehler still holds current records at the Henley Royal Regatta (Barrier and Fawley).
