About Our Team

DENNIS COX & TARA PETERSON  We are a full-service real estate team formed to help meet our clients’ needs 7 days per week. Our sellers rest easy knowing they will get more attention and exposure than if they listed with an individual agent. And our buyers get service on any day of the week.

For people looking to own property in this amazing place, we can understand why. The overwhelming beauty and endless amount of adventure possible in the Eastern Sierra is not lost on us. We love living the mountain lifestyle and help bring clients closer to doing the same.

We invite you to look search through all our local listings and contact us with questions.

It starts with finding a place to store your skis, mountain bikes, and fishing gear. And with real estate in Mammoth Lakes, you’ve already got location on your side. We will help you find the perfect location to help you reach maximum enjoyment potential: Ski-in/Ski-out, Golf course, Close to The Village, Views of the Sherwins, etc. We can show you any of the several hundred Mammoth real estate listings and we work to make your transaction go smoothly and quickly (please visit our Testimonial section).
For locals who are looking to sell property in and around Mammoth Lakes, you can trust your home, condo, or lot with us. We will promote your property appropriately, aggressively and directly to qualified buyers. We study the market and help sellers come to a price that works best for your timing and that captures the most value out of the market. Please visit the Marketing section of our website.
We work with a licensed team member, Eric Van Winkle.  Read his bio below.


I grew up in southern California and went to UCLA for a mechanical engineering degree.  On the side, I was a musician and rowed on the crew team.  I went on to work for Fluor Daniel, an international engineering company based in Orange County, CA.  Then I worked for Qwest Communications in Denver, CO, where I fell in love with the mountains.  I then left the engineering field to attend UC Berkeley and get an MBA. From Berkeley, I headed south again to get married and take a job with Intrawest in Mammoth Lakes, CA. Shortly thereafter I got my real estate license and have been practicing real estate full-time ever since.

I feel like I found my calling. I love the contact with a broad range of people and helping them find the perfect place to enjoy the mountains.  On the side, I am involved with Young Life (nondenominational outreach ministry for teenagers), Mammoth Christian Fellowship, and playing music in the Eastern Sierra Chamber Orchestra. My wife and I enjoy being parents and, when we have time, enjoy skiing, snowboarding, hiking, running, and volleyball. We have three daughters who help us look at life through kids’ eyes again.

taraABOUT TARA  I was born and raised in what used to be a “small town” in Southern California called Mission Viejo. Life was all about swimming for the Nadadores back then. In 1972, my family made its first trip to Mammoth and the love affair began. Ever since then, Mammoth and the Eastern Sierra has been my home away from home. I finally decided to make it my real home when I moved here after college in January of 1993.Mammoth almost became my home in 1987, when I had threatened to come up and be a “ski bum” just for one season after high school. Instead, I ended up spending those ten months working for a company in Grenoble, France. Upon my return, I immediately started working on my French degree (with business emphasis) at UCLA. A couple of years into my education I decided that I really wanted to go towards the health field and subsequently changed  my major to Kinesiology. My journey at UCLA came to an end in December of 1992, when I finally finished with Bachelor of Science degree in Kinesiology. All through college, Mammoth was still that home away from home, and being on the UCLA ski team made it that much easier to find reasons to come to Mammoth!Straight out of college, I was set on finally living the dream of living in Mammoth. After a number of jobs including driving shuttle buses, selling coffee and bartending for about five years, I eventually made my way into the real estate business when I started working for Intrawest in the beginning of 1998. Wanting to be able to serve all of my clients completely, I parted from Intrawest in 2001.

Practicing real estate here in Mammoth has given me the opportunity to do everything I like in a place I love, all the while meeting wonderful people. Mammoth has no shortage of recreational possibilities to offer and this, combined with the amazing beauty of this area, is what has drawn and kept me here. I have made Mammoth my home and now it is the home of my family as well.

Spending time with my daughters is time that I cherish.

It has brought me pleasure over the years to help other families and individuals find their “home” up here in the beautiful Sierras where they can start making memories and I look forward to being able to do that for you.

Eric Van Winkle, Team Member

I was born and raised in Orange County. Some of my best childhood memories were visiting my grandparents in the Eastern Sierras (in Walker 70 miles north of Mammoth). I am blessed by the love and support of my wife and four children.  Our three oldest children are independent and making headway into their adult lives.  Our youngest son attends Mammoth High School.

After a lifetime living in Southern California, my wife, youngest son, and I came to Mammoth for a weekend getaway to escape the 100+ degree temperatures.  This trip opened the doors to our relocation to Mammoth 3 months later.  After 7 years, we still pinch ourselves about how wonderful it is to live and work in this majestic location.

My entire working career has been about serving others. I have been a fire fighter and engaged in some aspect of customer service for over 30 years. I worked in the grocery business, Nordstrom, fire departments, and ran my own business as an RV component sales representative. I know how to provide top-level customer service and I am able to provide that to people wanting to find their mountain home. As my wife and I say there is never a bad day in Mammoth just look up to the mountains. We are avid downhill and Nordic skiers in the winter and enjoy RV camping, backpacking, hiking and road biking in the summers. We are active members of Mammoth Christian Fellowship. I have a fresh outlook on living and playing in the Eastern Sierras and can help you find your ideal primary or vacation home.

I am the newest member of the team! My journey has lead here with me working towards a real estate license. I will be licensed later this year and I hope to help the team as a licensee. My wife and I found our way to the Owens Valley after getting married in 2020. We have often visited when we were younger and have made invaluable connections with this area which are what brought us here.

I graduated from Loma Linda University in 2017 and have been working as a physical therapy assistant in a variety of clinical settings. My goals are to help others live their lives more fully and reach their potential. This aim will assist me as I transition into real estate work. I hope to bless other people with the skills I am learning and build relationships that provide value for others!

Ruth Hensley, Team Member

I have been a resident of the Eastern Sierra mountains for over 30 years and know the benefits of living in this wonderful place where I married, raised my two kids, and grew my career as a teacher in the Mammoth Unified School District.  As a real estate agent, my focus is on top-notch customer service and assisting buyers and sellers reach their real estate goals.  I enjoy sharing my knowledge of Mammoth Lakes and surrounding towns with my clients and have an intimate understanding of the neighborhoods that make up Mammoth and Crowley.

Having served on the Snowcreek HOA Board of Directors and Crowley Lake Community Water District, I have developed a deeper understanding of the complex issues of home and condo ownership in our community. My competence in the field stems from my BS in Business Management from City University, Masters Degree in Mathematics Education from the University of Texas, and my work in the US Naval Reserves. My unique experience and education have given me the necessary skills to handle the technicalities of any real estate deal. This combined with my desire to form connections with my clients makes me the perfect addition to your real estate search and purchasing journey. Choosing me to represent you means you will also benefit from the expertise and knowledge of the Dennis Cox Real Estate Team for exceptional service.
