Welcome to Modderman Service, Inc.

About Us
Staff

We are a 2nd generation family run facility and have been in the same location in Mountain View, CA for over 35 years. Our Shop was first opened in 1971 by Porsche trained and certified Master Mechanic Willem Modderman and brothers Hans and Ronald. After many years of tutelage and formal training at De Anza Auto Technology, the business was passed on to myself, David R. Modderman. Like Porsche, we strive to provide our client's with the highest levels of integrity and satisfaction. We invite you to call or visit for an assessment of your Porsche. We understand the passion that surrounds the marquee and the long-term relationships Porsches create with their owners. There is no reason this same attachment shouldn't be forged with the same people who service your Porsche in order to maintain its safety, performance, and value long term. Whether you are looking for basic maintenance of a pre-A 356 or want to prepare your late 911 (996) Carrera for Club Racing, we can assist you in your quest. We respect the fact that you have other choices for care and service of your Porsche and sincerely thank you for taking the time to visit our site.

We welcome any questions or comments you may have and look forward to meeting you personally!
