The Hammer Institute for Anti-Aging Medicine was founded in 2000 by Eli J. Hammer, M.D. For over 23 years, Dr. Hammer has been treating patients from Arizona and from all across the United States. The Institute moved locations from North Scottsdale to its more centrally located address in Phoenix, in June of 2009.

Our impressive office design is warm and welcoming, decorated with casual elegance in a relaxed and intimate atmosphere. Designed with spaciousness and comfort in mind, the ample conference room allows for hours of patient education and consultation with Dr. Hammer.

We are proud of our office, and our staff, who are dedicated solely to providing valuable, personal attention and high quality medical care.
