Woman Centered Counseling


Chantell Prestcott-Hollander, M.Ed, LGPC, NCC

Chantell Prestcott-Hollander grew up a military brat and the oldest of 8 children. She is happily settled in the DC area with her husband and has two teenage boys. 

She received her B.A. from Brigham Young University-Hawaii and her Masters from The University of Massachusetts-Boston. Chantell is a licensed counselor in Maryland and also holds National Board Certification as a counselor. She is a Yoga instructor as well as a Krav Maga black belt and Personal Trainer.


Chantell started her career in education, teaching 18 years ago. However, she felt she could be more impactful individually with students as a counselor. In 2011 she pivoted her career and began her Masters to follow this dream. She spent most of the last decade working in an all-girls school, where she draws on first-hand experience and access to the latest research on the development of girls and women to inform her practice. She is committed to understanding the unique ways women can grow stronger through working, learning and playing together in female-centric communities.

Chantell is equally passionate about helping women uncover their strength on the outside as she is inside. She has spent well over a decade teaching and training women in fitness and self-defense. She has seen first-hand at Krav Oz, (the self-defense and fitness gym she operates with her husband) the potential physical training has to foster resilience and growth for women, especially those who have experienced trauma.

Chantell's approach to counseling is person-centered, and her area of therapeutic practice includes but is not limited to; Adolescent counseling, Career and Lifestyle Counseling, Educational Counseling, Body Positivity, Behavioral Analysis, Life Transition/Adjustment, and Anxiety Disorders. She is currently training to become a Certified Clinical Trauma Professional. 

Chantell believes in a holistic approach to healing, wellness, and strength. She is passionate about guiding individuals and groups into deeper connection and growth through therapy, education, and physical training.

This approach works on the premise that individuals hold within themselves both the ability and the drive to live in the way that is most functional, most productive, and most fulfilling for them.  She believes the role of the Counselor is to provide a safe and genuine space and to join that individual in a process of uncovering and developing strengths while discovering their own healthiest way of doing life.

Although not an officially trained therapy dog Zoey has so much to offer in the form of love and inspiration.

Zoey, due to no fault of her own found herself surrounded by humans who didn't appreciate her. She, like so many women, was told she was 'too much.' Zoey even tried to run away at one point, but was rehomed to another abusive situation, and was once again met with neglect. Neglected because she was 'too much.'  Like many women who need out of a difficult situation, Zoey just needed a little help.


At Zoey's final visit to the shelter after a neighbor intervened, it was found out she has Lyme disease and heartworms. Her ears were disfigured from fly bites and her tail was badly injured.  But Chantell met Zoey via zoom (during the height of the COVID pandemic) and knew instantly that this dog was meant to share her home. 

Although Zoey still struggles with anxiety and is understandably fearful around many things, she is learning to be strong and brave. Every day she is facing her fears large and small. She is even on the road to a full physical recovery.


All Zoey needed was someone who understood her. Zoey has never for one moment been 'too much' she just needed understanding and love. She has overcome and is proving that her past does not determine her future, and because of that, Zoey is learning every day how to ask for what she needs, and get what she wants and deserves!  We hope Zoey will inspire you to do the same. 

You will occasionally find Zoey at the gym greeting guests or 'helping' Chantell train.
