Health and Wellness Center in Bucks County


Our Mission

Inner Spa is a holistic wellness day spa focusing on holistic, all-natural health from the inside out.  Through a spirit-filled belief that the body can heal and sustain itself, we provide a wide range of holistic services to aid individuals on their journey to find the mind/body/spirit connection that supports natural health and well-being.



At Inner Spa, we pride ourselves on our all-natural status.  After all, our goal is to remove toxins from your body, not put them in!  All of the products we use in our services are natural and organic.  We avoid product that contain chemicals, synthetics or were tested on animals.  Even the cleaning products used throughout the spa – except on equipment that requires hospital-grade cleaners – are all-natural.  What better way to relax, refresh and renew…naturally?


Wholistic Wellcare

We are committed to providing wholistic wellcare solutions for you to live your best life every day.  We call it “wholistic” because we offer alternative modalities focused on the whole person and wellcare because it is all about YOU!    Our principles have more than fifty years of combined experience inspired by relationships built on education, knowledge and integrity.  Each one of our certified, licensed therapists are here to help you thrive. 

Wherever you are on your health journey, our team of certified, licensed therapists and well-trained staff are here to meet you right where you are.  We invite you to look beyond traditional Western medicine, enhance your well-being, and join the many thousands of people who have already benefited from wholistic wellcare modalities.  When it comes to wholistic wellcare, you have a choice to create a happier, healthier, well-informed existence.

Spa History

Born from a personal health struggle with no explanations from traditional medicine, Inner Spa was founded on the signature service of colon hydrotherapy.  Following a 2004 unexplained diagnosis of chronic fatigue syndrome and a recommendation for prescription medication, founder and registered nurse Sharon Cross, wanted answers.

Lack of medical answers pushed her to take her health in her own hands, and she began researching alternative and holistic practices, the services we now call wholistic wellcare.  She started with a series of detoxification programs including herbal cleanses, dietary changes, colon hydrotherapy, and a host of alternative cleansing regimens.

Within weeks, she felt a significant difference in her health, and within a few months she felt like her old self.  It became evident to her that the underlying cause for her fatigue was toxicity, which she learned resulted in an overloaded, compromised system that manifested itself as fatigue.

Although trained as a nurse, the positive results she experienced from detoxification changed her nursing direction to focus on offering others the opportunity to enhance their own health through colon hydrotherapy and other natural cleansing methods.  Hence, our spa was born.

Continuing the Legacy

In 2011, Inner Spa was purchased by Cathy Agasar (formerly Windland), a local businesswoman who had more than 25 years of experience in marketing, consulting with businesses in a variety of industries to help them improve their performance.  When she came to a crossroads in her life, she decided it was time to step to the other side and become a business owner herself.

Cathy thought she was healthy, but after purchasing Inner Spa, she quickly realized just how unhealthy she was.  And so, like the previous owner, her journey to wellness began.  She started by becoming an I-ACT Certified Colon Hydrotherapist and has continued to study and practice all-natural wellness from the inside out.  Her experiences and knowledge have helped hundreds of clients find their mind/body/spirit connection through wholistic wellcare and natural healing.

Expansion & Service

In 2019, Cathy and her husband, Dr. Jerry Agasar, merged their practices to become Agasar Family WellCare at Inner Spa.  In doing so, they brought the three Cs of wholistic wellcarecolon hydrotherapy, cleansing services and chiropractic care – under one roof.  Together with their team of well-trained therapists and staff, the Center now offers a wider variety of services to address the stresses of everyday life and how they affect an individual’s health.   With a belief that the body can heal itself, Inner Spa is focused on wholistic wellcare customized to the individual needs of each client.  

Today, Inner Spa remains one of the area’s only certified centers for colon hydrotherapy, as well as other natural, organic cleansing and wellcare services.
