I specialize in endurance and ultra endurance coaching (marathon and longer distances). I work with motivated intermediate level runners who are looking for knowledge and guidance as they tackle a new distance as well as advanced runners looking for innovative, structured training as they work to set a new PR. Coaching with me will provide a customized progressive training schedule complete with daily running, strength training, and mobility recommendations. I will help you to build a solid foundation of fitness and guard against injury. I also hold a Ph.D. in sports psychology and provides expertise and support with the mental aspects of running, including race day planning and strategy, mindset coaching, and confidence building.


Working with a coach should be about more than just a training plan. Running, racing, and goal setting are incredibly personal activities filled with passion and joy, but also vulnerability and trepidation. Selecting a running coach is fundamentally about who you want to come on that journey with you. A coach should of course provide you with their knowledge and expertise on when to run, what type of workouts to do, how to strength train, and how to prepare for race day. A coach should also help you fit training into your life (after all, we all went pro in something other than running). A coach should help you notice and observe patterns that work for you or against you (training based, nutrition based, or otherwise). A coach should communicate with you often. A coach should expect and want you to ask for help rearranging your training week when life gets in the way. A coach should enjoy passing along professional and personal knowledge to help you avoid making the same mistakes they did. And most importantly, a coach should want to do such a good job, that one day you don’t need them anymore. Success as a coach is defined by more than helping you set a PR, it’s about helping you learn enough to become your own coach.

*My psychical training methodology is based on the training methods of Tim Noakes, Arthur Lydiard, Pete Pfitzinger, amongst others. My mental training methodology is rooted in positive psychology and cognitive behavioral tools.


I have been coaching since 2019 and I have worked with athletes looking to accomplish a huge variety of exciting goals, from qualifying for the Boston Marathon, completing an ultramarathon, climbing Mt. Everest, or setting an FKT. I have also conducted sports psychology and mental coaching sessions with several professional athletes, including members from the Olympic team. I also have experience coaching athletes struggling to come back from injury or setbacks.


I have been providing services to athletes since 2019, when I obtained my Ph.D. in sports psychology. Professionally, I love integrating my expertise in run coaching and sports psychology to provide all-inclusive support and guidance. Personally, I live part time in Denver CO and part time in Scottsdale AZ. I spend over 100 nights a year in my camper van in close proximity to beautiful running trails. I was a road marathoner for over 10 years and transitioned to running primarily ultras in 2018. Since then I have fallen in love with trail running. Currently I’m attempting to balance mountain running and fastpacking with competitive racing. I am the proud owner of two dogs who love running as much as I do.


I’ve been lucky enough to be coached by several incredible coaches who have had a big influence on me as an athlete and coach. Most recently I have been coached by Chris Hauth, former Olympic swimmer, turned pro triathlete, turned ultra runner. Chris has had a big influence on how I approach structuring a training program, the value of integrating strength training, and the importance of attending to the mental aspects of running and racing as much as the physical. I’ve learned the importance of frequent and honest communication between athlete and coach. The job of the coach is to help the athlete set goals and meet challenges, which can only happen if the relationship between the athlete and coach is strong. The athlete needs to feel empowered to share how training is going, including the challenges or days that are not going well. And the coach needs to listen and meet athletes where they are at.


I have loved running my whole life. I raced cross country competitively in high school and started running road half marathons and marathons when I was 18 years old. I have over a decade of experience racing road marathons and half marathons, including the Boston marathon. In 2018, I transitioned to ultra endurance (longer than a marathon) and trail running. Since then I have completed several 100+ mile races, including a 135 mile race across the Denali highway in Alaska. While not a professional runner, I typically compete for finishes in the top 5-10 women in larger races and I have earned podium finishes in many modestly sized events.


I hold a run coaching certification from ASFA. I’m also a NASM certified nutrition consultant and I earned her Ph.D. in psychology in 2019.
