John Fowler and Josh Greenberg began working together with the 2001 founding of the Montebello Capital search fund. Having met at Stanford Business School in the late 1990s, they shared a passion for entrepreneurship and a common vision of what it takes to build a great company. After securing the financial support of a diverse investor group, and conducting more than a year of research, they acquired specialty shipping company Aero Logistics.

After purchasing Aero Logistics in 2003, they became intimately involved in every aspect of the company and focused on developing and empowering team members through a corporate culture of exceptional customer service. They brought a fresh, outsider's perspective to the business and a level of innovation and operational excellence that at the time was rare in the shipping industry. Over five years they increased Aero's revenues more than five-fold.

Fowler and Greenberg formed Montebello Holdings in 2008, upon their departure from Aero Logistics. Since then they have made minority equity investments in several private companies. In addition to overseeing these investments, from 2009 to 2014 they ran HealthCPA, a healthcare services business acquired by a leading revenue cycle management company in 2014.

In March 2015, Montebello Holdings partnered with Alpine Investors on the acquisition of Risk Management Strategies, a San Diego-based provider of outsourced employment and risk management services. Josh Greenberg is now serving as the CEO of the company.  

Prior to forming their partnership, Fowler and Greenberg held a variety of operating and leadership roles in both the public and private sectors.

John has been a successful operator in organizations ranging from high tech start-ups to the U.S. Government. Prior to working with Josh, John worked with Idealab Silicon Valley and also as a management consultant with William Kent International, advising clients on international acquisition opportunities and market entry strategies. He began his career in Washington, D.C., as a Congressional Affairs Specialist for the U.S. Trade Representative. John received both his A.B. in International Relations and his M.B.A. from Stanford University. He served as CEO of Aero Logistics from 2003 until 2008 and as CEO of HealthCPA from 2009 until 2014. Since then John has served as co-founder and CEO of Kezar Life Sciences, a biotechnology company focused on the discovery and development of small molecule drugs to treat autoimmune disorders and malignancies. 

Prior to serving as Chairman and President of both Aero Logistics and HealthCPA, Josh played a variety of roles in multiple industries with an emphasis on marketing, finance, and business strategy. As a product manager at Intuit, he led cross-functional teams in the development and marketing of new features for the Quicken.com website. Before Intuit, Josh was a strategy specialist with Charles Schwab, where he managed business strategy projects on behalf of Schwab's executive management. He began his career in Public Finance where he aided government clients in raising over $1 Billion to support infrastructure projects. Josh received his undergraduate degree in Economics at the University of Virginia and earned his M.B.A. at Stanford.
