CEO Message

To be a company that contributes for the improvement of health of the whole people in the world with the technology of medical equipment beyond 80 countries..

Hello. My name is Lee Jae-Hwa, president of DS MAREF.

Starting with Daesung Machinery Trading in 1986, we have grown and developed as a representative pneumatic medical equipment manufacturer in Korea today overcoming lots of difficulties with the calling of improving the health for human beings. Most of all, the whole executives and employees of DS MAREF has constantly worked for the health of people rather than the company’s profit and to be born again as a medical equipment manufacturer globally rather than staying in the domestic market.

As the result, we keep the pace with famous global companies as a representative pneumatic medical equipment manufacturer in Korea recognized our technology of DVT prevention equipment chosen as the world best item in 2004 and exporting to about 80 countries. In addition, the whole workers work hard to realize the customer impression through securing the perfect quality. We grow as a brand which everybody in the world can trust and use safely by strengthening our technology based on the strict medical equipment quality standard and certifications around the world.

To reward for the interest and love from people who trust and use DS MAREF until now, we prepare for another 100 years in the future. We will grow as a medical equipment manufacturer which represents Korea prioritizing the value of life continuously.

Thank you.

But we did not give up and knocked on the world market. If only 5 minutes was given, we came to visit anywhere and let them know about us.
We went to exhibitions in over 40 countries around the world and informed them of Doctor Life until we were thirsty.
