About Mary

I am a Certified Personal Trainer and Weight Management Specialist. I have five years of experience training adults of all ages with various health conditions and specialize in weight loss, women's health, low back pain, and functional training. Most of my clients are women between the ages of 45 and 70 with underlying health conditions. As your trainer, my goal is to help you develop healthy habits and independence to reach all of your fitness and nutrition goals. My workouts are completely customized to your specific goals, interests, and current fitness levels. I provide fitness and nutrition homework in between sessions to maximize your results. My training style is very positive, supportive, motivational, and educational. The price for each session includes me traveling to you, the necessary equipment, and homework in between sessions to keep you working towards your goals. My clients mean the world to me, and together we will help you achieve all of your fitness goals. I look forward to meeting and working with you!


My favorite client story

One of my clients has struggled with weight loss and a sedentary lifestyle for years. As a cancer survivor with a knee replacement, she wanted to make exercise and a healthy diet part of her daily life. Since working with me, she has lost over 20 lbs in four months, has made exercise part of her daily life, and has found a new confidence in herself, her capabilities, and her strength. A side benefit for her has been seeing daily activities get easier and easier. Seeing how happy she is has been so gratifying.

My favorite exercise

Push-ups - they are tough but they are functional and work so many muscles!

My favorite quote

"Believe you can and you're halfway there."

My training philosophy

My training philosophy is to set a well-developed plan and adhere to it through hard work and dedication, pivoting as necessary to achieve your goals. I will do my very best to ensure a safe and effective workout program for you.

My training experience

As a student at the University of Maryland, I trained many clients of both genders and all ages from 18 to 74 with a wide range of goals, health issues, and preferences. After taking a break, I am now doing in-home personal training with an emphasis on partner training, women's health, weight loss, and strength building. I work with all types of health conditions including high blood pressure, low back pain, post-surgery, plantar fasciitis, wrist and knee problems, cerebral palsy, scoliosis, sciatica, shoulder and neck pain, asthma, diabetes, and cancer remission.

Mary was a very motivating and energetic personal trainer. She always had fun workouts planned for me around campus that utilized the nature of the landscape. From running up and down the stairs of Comcast Center to running backwards uphill to lifting weights at the gym, it was never a dull session. I always left feeling refreshed, sweaty and sore for days. I lost 10 lbs in the time I worked out with her and felt more energized. Mary is very effective and drives results in a fun way. I strongly recommend her as a personal trainer.


Mary is very caring and attentive to what each client needs, what their limits are, and how far she can push them. She encourages and motivates me to do better, and yet she knows how much I am capable of. She’s always on time and ready to have a fun workout!


Mary was my first personal trainer (back in my college days) and she definitely gave me a push start to my workout regimens. Sometimes, I would feel my legs pulsing after her intense workouts. She always knew how to encourage me to try harder or go longer to really get a good workout. She is also a very sweet person and a pleasure to work with.


Mary is kind, supportive, knowledgeable and so much more. She gets to know you and your goals and makes them happen. She holds you accountable but also understands that you have a life and is able to help you find a balance so you can stick to the program. Her workouts are challenging but not intimidating. She actually makes working out fun (a sentence I never thought I would say). What I find most impressive is her knowledge of the human body and different work out methods. She is constantly keeping up to date with the latest research and imparting that knowledge to her clients so you are working out smarter not harder. My sister and I are looking forward to many more sessions with Mary.

Mary is an amazing personal trainer! If you're looking for someone to motivate you on your fitness journey, provide knowledgable guidance, and keep you accountable, look no further! Mary was a perfect fit from the very beginning. Highlight: My favorite part of working with Mary is her extensive knowledge of the human body and fitness and her ability to teach me. I love learning the "why" behind the exercises, number of reps, when I increase weight, and when we mix up the homework. It's clear that Mary has a plan and logic behind everything we're doing, which means I've gotten to see results much faster. Consultation: On our consultation call I was able to explain my goals and learn more about her training style, which is highly personalized and focused on sustainable, continuous improvement. At the start of our first session, Mary took extra time to understand my motivations and what success looked like to me. Sessions: The sessions are challenging, but Mary is always very attentive to check in with how I'm feeling and if I have any pain from previous injuries. For me they were a mix of cardio and weight training, but could vary depending on your goal. Mary was also willing to work with me on designing a program that I would enjoy and do consistently. She brings a lot of energy to the sessions and helps motivate me to do "just two more" reps. Results: In the first few weeks, I saw improvement in my muscle strength, cardiovascular endurance, and overall wellness. My goal of just wanting to be fit and "live to 100" wasn't an easy one to define, but Mary was able to craft a workout plan that fit the bill. I was so happy after my initial session package, that I added more.

Mary is a great trainer. She is positive, encouraging and never makes you feel bad if you are struggling. She adapts to your needs and really listens to your goals. She tailors the work to any physical limitations, gives you great ideas on alternative exercises, and follows through. Extremely responsive and communicative. My experience with Mary has been great.

Mary is excellent, I highly recommend her.

Mary is an amazing personal trainer who shows a clear passion for fitness and makes exercising fun. She created a fitness plan for 4 participants for a fitness study and was able to create a workout that would be challenging, but fun and never got boring. All of the participants showed an improvement, thanks to Mary’s workout plans. She was extremely supportive, knowledgable and easy to work with. I would highly recommend Mary as a personal fitness trainer for anyone who is looking to begin a workout routine or improve on their current workout routine!
