What our Boston athletes have to say…

  • boston running coach

    "Emma helped me rehab from knee pain during a marathon training cycle. I not only fully recovered in time for the race, but felt stronger and more prepared after working with her. She also does dry needling, which for me made a big difference. She's patient, knowledgeable, and an excellent listener. Highly recommend Emma and Sisu Boston!

    Auva S., ultra-marathoner

  • "Emma is the reason I was able to run my marathon in a personal record time. She took my training to a whole new level, from both a performance and enjoyment perspective. Her knowledge and attention to detail was beyond anything I've experienced working with other coaches. I highly recommend Sisu Boston to anyone from beginner to advanced runners who are looking to unlock their potential!

    "I received exceptional coaching from Sisu Boston. Emma is a wonderful, caring, and knowledgeable PT and coach and made my experience so enjoyable. She encouraged and motivated me to achieve my goals and I'm proud to say I am now an Ironman finisher. Wouldn't have made it without her coaching expertise. Thank you!!"

    Working with Emma completely changed how I approach running and training. I've been running for years but never thought I could get faster after turning 40. Emma not only gave me a plan that fit my busy life, but she also helped me understand why each workout mattered. Her advice on pacing, nutrition, and recovery was spot on and I felt stronger and more confident each week. On race day, I crushed my half marathon PR, something I never thought possible at this stage in my life. If you want to improve without burning out, Emma is the coach for you.
