    I have been with Nancy for a couple of years now. Over that period of time I have been able to increase my fitness to the point that I can participate in activities I could never have done without specific training help. I can kayak and get out on my own with my tricep strength. I can move more flexibly-- I can even lift a bunch of groceries out of my car and lift them over my head to reach the close button on the hatchback! She makes it fun and I literally never would be as fit on my own. She models such respect for each and every client as well as deep knowledge of how to improve health without injury. She is such a unique trainer... don't go to her since then I won't get as much of her time!!

    Nancy knows all the science behind what she tells you to do but never intimidates you with it. She pushes you to grow in a way that is so gentle that you don't even realize it... until you can't walk the next day. She cares so much about her clients and will wrack her brain to modify an exercise so that it is something you can do. She is hilarious and quirky and sweet and the hour with her flies by. She is so good that I take classes that I have previously had no interest in, just to work another hour with her and let her speak her wisdom into my life. Also, her nails are always bomb.

    I started going to the gym back in March and I can tell you if I hadn't walked in to Nancy's class first I probably wouldn't have come back.
    Her high energy & friendliness kept me coming back for more.
    She makes it a point to not only know everyone that walks in her class but she also lets you know what part of your body you are working.
    Also making it a point that we are all different & only work as hard as our bodies can handle.
    Ive taken a few other classes she has and it's amazing the knowledge that one person has in of these different areas.
    She loves what she does and she loves all of us as well.
    I highly recommend and of Nancy's classes she's pretty amazing!!

    If you are looking for a great group x instructor or a personal trainer, stop looking, you are in excellent hands with Nancy! She is truly amazing and cares about each person she is helping. If you are looking to lose weight, build muscle or have a fun time, this is what you are going to get! She teaches in lots of different formats, so try them all before you decide which one you like the best. She is also a great mentor and has helped push me just enough to cross over my own line and break out into the fitness world. Through her support and encouragement, all things are possible!
    Thank you Nancy, you will never know how much you have helped me!

    For the past 20 years, I have been a member of gyms. I like trying the broad range of group fitness classes that are offered, I like weight resistance training several times a week, I like the comraderie and benefit of small group personal training, and I've hired a handful of personal trainers along the way when I have a specific goal in mind. For almost 10 years, I've been an instructor and a manager at a year round swim school and I've even become a Zumba instructor along the way. All this is to say: When it comes to fitness and fitness professionals, I've been around the block a few times.

    Nancy is a standout. I've never met a trainer as knowledgeable and as personable as Nancy. I've been in her small group CrossCore classes, and I love how creative and knowledgeable she is. She has more fitness wisdom in her little pinky than I could dream of having in a lifetime, but she doesn't lord it over anyone. She is her client's cheerleader and support. Her workouts are simple but effective, and challenging to each person right where they are at. Nancy, just by being herself, doesn't make anyone feel bad about their current abilities or non-abilities. She includes everyone. She makes goals attainable. I feel like I need to write everything down after having a session with Nancy because my brain will explode trying to remember all the great things she showed me. She also listens, so if there is a goal that someone has in mind, even if it's as simple as being able to do a pullup for the first time, she helps them reach that goal. She is understanding and accepting; she sees people holistically and know that there is more to everyone than just their time in the gym. She has an eye for detail and knows what to look for when it comes to effectiveness and safety; she can see when an angle of a joint needs to be moved "just so" to get maximum benefit from an exercise.

    I've been in Nancy's Zumba classes and she brings all of the above to these classes too. She engages and leads her class beautifully. She weaves great fitness moves throughout her choreography. She shows many different levels so anyone can feel successful. I've seen her at Zumba trainings and I can tell that she is interested in further learning. Nancy doesn't stay stagnant or rest on her current knowledge.
