Mandy Dieter has been working as a personal trainer with my son Anthony since September 2023 and with me since October. Mandy is very flexible, patient and encouraging. She is wonderful at guiding, coaching and demonstrating what should be done. She is knowledgeable about so much related to health, wellness and working out. My son Anthony has Down syndrome and l am very particular about who l trust with him. Most of the time I am NOT with him when he works out with Mandy and spends time at the YMCA. Since getting to know Mandy, I do not worry about Anthony when she is at the YMCA even if he is not scheduled with her. Mandy is a great communicator and very knowledgeable about working with adults with special needs. She will share his successes as well as her concerns if she notices something off with Anthony. Anthony loves her, but more importantly I trust her. I have watched how she interacts with Anthony, and it is exactly what he needs, high expectations with gentle guidance and support. She is great at empowering him to be independent and he has shown so much growth, not just in the exercises, but in other ways as well. I am grateful that Mandy is there for him.

My name is Dolores Parsil. I live in Lancaster. I am married and have two children and five grandchildren. I am a retired public high school teacher. I have known Mandy Dieter for the past year. She is my personal trainer at the Lancaster YMCA. We work together for 45 minutes two or three times a week, and I have come to value my sessions with her as a very important part of my life. I have come to know her very well. Mandy has been my trainer (first one in my life, and I'm 79) since February of last year, and I am very pleased to be working with her. I wasn't sure I'd stick with a trainer, given my age and previous lack of experience with one, but we're still going strong, and that's because Mandy continues to keep me interested and make me stronger. She is very flexible with scheduling and is always understanding when I have to cancel or change my time. The workouts are varied and interesting, and she models the exercises for me and does them with me. She challenges me but she does not push me too far. Mandy suggests activities and exercises for me to do on the days I'll be absent, and she has even made several videos demonstrating some. Mandy’s knowledge of the physiology of the human body amazes me; she explains, in layperson’s terms, why she’s having me do something in terms of muscle groups and their interconnectedness. I never feel inadequate or discouraged because Mandy’s tone of voice and demeanor are always pleasant and encouraging. She is patient, encouraging, and complimentary; she makes me feel successful. She's an excellent trainer, and I am grateful to be working with her.

My husband, Charlie Worrall, and I so appreciate the care and personal involvement you have invested in improving our physical progress that we want to share with you in this note, why we feel our association with you over the past year has contributed in such a profoundly positive way to how we at our senior years… as a time of possibility, and not the limiting, creeping physical reality that many folks give in to. We are no longer the youthful couple of years past. I am 78 and Charlie is 79. We came to the YMCA to improve our balance, flexibility, energy levels and develop habits that will serve us well so we can continue our active community volunteering and the other ways we participate in life. For sure your professional expertise in exercise, movement, body physiology and aging has played a strong role in the progress I have made as your client. This letter, however, is meant to thank you for what you as a person have done for me, and for us together at the YMCA. You are a kind, involved, encouraging, caring individual who meets people where they are and helps them move beyond that. You are aware of developmental issues that slow progress but which can be reversed; you have a way of inspiring trust that is heartwarming; your compassion for one’s changing needs is also inspiring; and your patience helping others learn more productive methods that will benefit them is, well…, most inspiring. Both of us are grateful we found you, and look forward to more progress under your guidance.

As a friend and professional client of Ms. Mandy Dieter, I am writing to vouch her as an honorable and well-intentioned individual with the highest moral standards. Ms. Dieter has been working with me in the capacity of a physical coach for over a year working together twice per week. ln my experience Ms. Dieter is an honest hardworking, and genuine person who strives to maintain a high standard of excellence in her work. Ms. Dieter is consistently reliable. She has never missed an appointment or misrepresented herself to me. l've been specifically impressed with Ms. Dieter commitment to me as her client. She is patient, encouraging and helpful. While working with me, she keeps an eye out for the safety of other clients in our work environment. She is gentle, respectful and seems to always look for the positive side of any situation. I know Ms. Dieter loves her family, always putting them first. l've heard many endearing stories of her home life and activities with her children. She is committed to their well-being while she maintains her professional position.

It is my pleasure to offer the following client testimonial on behalf of Ms. Dieter. I first met Ms. Dieter in the summer of 2022 at the City Center YMCA in Lancaster, PA. She provided a few one-on-one strength training sessions for me at that time. I resumed strength training with her in November 2023, and I would estimate that I have trained with her on average at least once a week. My work schedule and overseas business travel for several weeks a time were the only reasons for the gap in training periods. I am incredibly grateful and fortunate to be one of Ms. Dieter's clients. Her professionalism, expertise, and commitment to her clients' well-being are exemplary and truly appreciated. She is on time, flexible with scheduling, and has always treated me with courtesy and respect. Ms. Dieter also takes time to explain in detail the purpose of each exercise, watches carefully how I perform the movement, and has a gift for offering a powerful balance of support and challenge in building fitness. My trust and respect for Ms. Dieter grows with every interaction because of her expertise, care, and character.

I have been training with Mandy Dieter for the past several months. Under her guidance, I have been able to achieve a level of strength and discipline I had not anticipated. In short, she inspires me. Her skill, knowledge and instinct truly set her apart. As I tell all my friends, I have the "best trainer on the planet."

Rick and I are very happy that Mandy is working one on one with Jackie. Mandy has helped Jackie increase her overall strength. She has helped Jackie enjoy being active; and by spending time with each other every week, she and Jackie have developed a beautiful friendship.
