Edward G Detwiler

With more than 30 years of experience, Edward G. Detwiler & Associates, Ltd. provides appraisal services nationally and internationally.  We specialize in valuations of high-tech, medical, scientific, and ancillary equipment, along with forecasting and research reports. 

We are considered "The Experts" in the healthcare field when it comes to tangible asset valuations.  Our team performs a wide variety of assignments, ranging from projects as small as a single asset or an individual physician’s practice, to valuations of the equipment in entire hospitals or public companies in merger situations.  From large to small,  we can do it all! 

 We Follow the Science

Our research is what sets us apart because “we follow the science”.  Our team has the knowledge of what the world is doing scientifically with diagnoses and cures of different diseases.  This allows us to have a competitive edge on what new medical technologies are being introduced and what that can mean for the industry.

With our knowledge, research and expertise you'll receive the most accurate valuations on tangible assets; something a depreciation schedule won’t provide for you.
