Today it is our pleasure to announce the addition of Custom Ultrasonics to the Wassenburg Medical family.

December 31st, 2021
Dodewaard/The Netherlands, Ivyland/PA/USA

Wassenburg Medical has purchased the assets of Custom Ultrasonics effective December 31st 2021.

Custom Ultrasonics Inc. (CUI) was established in 1981 by Frank J. Weber to design, manufacture and distribute automated systems to clean and high-level disinfect complex devices including multi-channeled flexible endoscopes. The company is currently led by Alicia Nakonetschny.

Wassenburg Medical B.V., originally a family company, is now in a joint venture with Hoya since 2013. The company was established in 1984 by Gerrit Wassenburg and has developed into a highly regarded specialist in all aspects of automated endoscope reprocessing. In 2002, Gerrit passed the torch to his sons Arno and Ronald, who successfully lead the business today.

Custom Ultrasonics activities will be assumed by Wassenburg Medical Inc. including the staff, who will continue to serve the customers with the product portfolio they are familiar with and have the opportunity to market the Wassenburg portfolio in the future.

Ronald Wassenburg, CEO Wassenburg Medical B.V.:

“This acquisition is an opportunity for Custom Ultrasonics to expand their product portfolio with our products. For us, it is a window to the US market. We are thrilled and excited to work with Alicia, Mike and all CUI team members. We look forward to a prosperous future together.”

Alicia Nakonetschny, CEO Custom Ultrasonics Inc.:

“We are pleased and enthusiastic about the synergies generated between Custom Ultrasonics and Wassenburg Medical. Wassenburg Medical Inc. will combine and enhance an offering of legacy and new products to customers, while affording the opportunity to expand and strengthen the US workforce. We are looking forward to a new era of endoscopy products for the US market.”

We are confident that this alliance will create additional growth into the US market for both companies and, most importantly continuing to provide a safe endoscope for every patient
