Company History

Dr. Boris and Mrs. Marsha Karlin created Mainline MDS in 1995 as a side project. Dr. Karlin, a dentist by profession, and Mrs. Karlin, a dental hygienist, brought their years of experience and knowledge to the healthcare industry.

What started as a two-person company running out of a home became a well-respected and established operation employing a team of over 20 people. As the company has grown and continues to grow, the values of a family-run business are still in place to this day.


At Mainline MDS, our mission is twofold:

  1. To provide our customers with quality Dental and Medical supplies while ensuring a customer-oriented buying process through our team of product specialists and logistics operators.
  2. Through research of products and various marketplaces, we can identify quality manufacturers and introduce their innovative and novel health products to the North American market.
