MEDICAL PRACTICE PURCHASING GROUP (MPPG) was founded in 2004 by Dr. Brian Greenberg, a Pediatrician and Allergist in Agoura Hills and Tarzana, California in order to help physicians with the high cost of medical practice.

Beginning with four practices and a Sanofi Pasteur contract, MPPG has grown to serve many physicians in a wide variety of specialties with an expanding choice of key money saving contracts. Since 2006 MPPG has added contracts with:

  • Merck, Pfizer and Medimmune for vaccines
  • CAP (CA only) and Pinnacle Brokers (national)  for medical liability coverage
  • ClearGate for merchant services
  • Henry Schein for medical supplies
  • Staples Advantage for office supplies
  • Farmers for Insurance
  • Medical Waste Management for medical waste (CA only)

Please see Partners & Products for a complete listing.

Feedback from MPPG members affirms that our mission of saving physicians money is critical to their ability to practice in today’s financial climate. It is MPPG’s continuing goal to increase physician profits and reduce stress – we believe that doctors work hard enough. Dr. Greenberg currently oversees the day-to-day operations of MPPG in addition to practicing medicine full-time.

Brian K. Greenberg, M.D.
President, MPPG

Dr. Greenberg, in medical practice since 1991, received a BA degree from the University of Pennsylvania, his medical degree from University of Florida, and completed his residency in Pediatrics and Fellowship in Allergy and Clinical Immunology from the University of California, Los Angeles. In addition to treating Pediatric patients, Dr. Greenberg provides care for a large number of Pediatric and Adult Allergy patients focusing on prevention and education. Dr. Greenberg is married and the father of three daughters. Dr. Greenberg has been involved in education for many years and is currently the chair of the University of Pennsylvania’s Alumni Interview Program for Ventura County and Malibu. He additionally has a wide array of interests including politics, traveling, gardening, hiking, and mentoring youth.

As a Pediatrician in practice for over twenty years he knows firsthand how hard it can be to run a successful medical practice. As if declining reimbursement isn’t enough, costs keep going up with no end in sight. Dr. Greenberg started MPPG to save money not only for his medical practice, but those of his colleagues as well!
