Serving the Mid-Atlantic Region with cost effective Ultrasound Solutions

From the corporate world to the small business world, Stuart Latimer, Bryan Hoffman, and Alan Pettenati achieved their greatest dream. This dream was to enter the ultrasound industry by creatingTrisonics, Inc., and establish itself as a leader in ultrasound diagnostic equipment sales and service.

Trisonics opened in January of 2004 providing exceptional personal and reliable medical diagnostic ultrasound service and sales to its customers.

At this point in time, Trisonics services businesses located in Pennsylvania, Delaware, Maryland, New Jersey, New York, Ohio, West Virginia, and Washington DC. However, as the business continues to grow it will also expand its geographic target market.

Just recently, Trisonics was named to the exclusive Inc. 5000. Coming in at 3,799, it is now ranked among the nation’s fastest-growing private companies. The Inc. 5000 represents the most important segment of the economy – America’s independent-minded entrepreneurs. The list is ranked according to percentage revenue growth for a four year period. To qualify, companies must have been founded and generating revenue by the first week of the starting calendar year, and therefore able to show four full years of sales. Additionally, they had to be US-based, privately held, and independent as of December 31 of the last year measured. Revenue in the initial year must have been at least $200,000 and at least $2 million in the most recent year.

Trisonics began operations in 2004 with total sales of $850,000 and in 2009 sales grew to $3,500,000.

The Clarion University SBDC helped us put together a strong business plan that eventually was the key to funding our business"

The Inc. 5000 debuted in 1981 as a ranking of the 100 fastest-growing companies in the United States. The following year it expanded to 500 and, in 2007, the list of the top 5000 was inaugurated. Through each evolution, Inc. has sought to recognize the creativity, dedication, and hard work that entrepreneurs put into building their companies. Despite the fact that most of this year’s measuring period (2006-2009) took place during the recession, Inc. 5000 companies generated $322 billion in revenue, a 50 percent increase over last year. The companies also employ a record 1.4 million people. The success of Latimer, Hoffman, and Pettenati was celebrated at the 2010 Inc. 500/5000 Conference & Awards Ceremony held in Washington D.C. from September 30 to October 2. Other popular companies on the list include Pandora, 7-Eleven, and Toys “R” Us.

Alan Pettenati first met with the Clarion University SBDC in January of 2004 with the goal of creating a business plan for Trisonics, Inc. Since then the owners of Trisonics have utilized the professional business consulting services of the Clarion University SBDC to assist with creating comprehensive marketing and strategic plans, human resource material, and b2b research.
