Professional Summary

As a vice president based in Ontario, California, I have been with Colliers International since 2011. Specializing in industrial investment and user sales on small to medium industrial properties in the Inland Empire, I am committed to building collaborative and long-lasting relationships with my clients. Taking pride in going beyond client expectations throughout each transaction, I strive to overcome any obstacle by thinking outside the box. As a result, our team has built a reputation for being one of the most knowledgeable, resourceful and hardest working teams in the Inland Empire.

Prior to Colliers, I studied economics at Occidental College, gaining experience at several real estate firms along the way. At Colliers, my career has evolved to effectively support a variety of clients and deal types. From tenant representation to landlord representation, I have extensive experience in investment sales, tenant leasing, land deals, development opportunities and market analysis.

Whether in the office or outside of work, I am optimistic and outgoing—someone you can trust. I enjoy spending my free time with family and friends, who will tell you that I’m always up for an adventure or a game of golf, soccer or squash.

We began marketing our property in Rancho Cucamonga in the Spring of 2014. It was a well maintained 55,000 warehouse facility with a prime location. Our listing was placed with Lee & Associates. Lee is a fine professional firm that we have no specific issues with; however, we did not get any traffic to speak of nor did we get the feeling that there was any proportional marketing of the property. That being said after six months we made the decision to terminate our relationship with Lee and move the listing with Colliers.

Over the course of the next four to five months the property experienced high traffic as a result of a robust pin point marketing effort by Colliers. As opposed to our previous experience we were in constant contact with Brad Yates and Stefan Pastor no less than weekly and frequently two to three times per week. There was a continual focus to fine tune strategy, making the property visible to the target market and sharpen the price point all of which resulted in the ultimate sale of the property in late May of 2015. Concurrent with the sale process Colliers was also instrumental in assisting us with the purchase of 100,000 square foot facility. At the risk of sounding like we are heaping vague platitudes upon Colliers I can honestly say that their effort, knowledge of the market and startegy made the difference and resulted in a quick sale of the property. Please do not hesitate to contact me directly if there is any other information that i can provide.
