“27 years ago I embarked on my journey and ‘green connection’ and I’ve been passionate about the health and wellness benefits of green and clean living for a very long time. The research in this area has intensified in recent years, and I am very grateful that more and more people are recognizing the personal and environmental benefits of living clean and green.”

– Rena Feldman, 
Founder of Rethink Function

Small changes, big difference

Be it a cleaner household product, a more natural storage container for leftovers, or an ethically-sourced material for your home organizing system, little alterations go a long way. As you make moves towards a greener way of life, you also take strides towards better health for you, your family, your home and the environment.

Clean & Green Products

Did you know that many of the products we use in our homes contain toxins and chemicals that are not just harmful to the environment, but also potentially irritable to our lungs, skin and eyes?

It doesn’t need to be that way.

There are greener options out there that really work!

Rethink Function has the knowledge to recommend healthy and green alternatives that meet your needs and expectations. We’ve done the research so you don’t have to. From skincare to home cleaning products, to natural disinfectants, our team is here to guide you in the right
direction so you can achieve meaningful change in your space.

Why live cleaner and greener?

At Rethink Function, we believe our lives are enriched as we become cleaner, greener and healthier consumers. Even the smallest of adaptations in the products you bring into your space can have a positive impact on your wellbeing in the following ways:



  • Improved air quality
  • Pure home environment
  • Decreased allergens
  • Reduced irritants
  • Environmental benefits
  • Less waste

Hand in hand

Over the years, we’ve found that organizing goes hand in hand with adopting healthy, green practices. While they are two separate concepts, they also share a common goal: to live optimally.


When you strive for organization and function, you also tend to be driven by healthy and environmentally conscious decisions – and vice versa.


Rethink Function ties it all together to help you achieve your living and working goals from every angle.

Today, research and development in clean and green living is readily available, and greener, healthier, eco-friendly products are widely available.

Client Testimonials

"I began working with Rena approximately 13 years ago when we hired her to help organize our kitchen and home office - it was a big job but well worth it, and the systems she put in place have survived two house moves!  Since organizing our house, Rena has introduced me to many products and systems that are "clean" and designed to make our lives healthier and easier.  Rena is very passionate and well informed about all the products that she recommends - she puts in a lot of time and energy researching and testing every product before giving it her stamp of approval!  Over the years, I have come to consider Rena a friend and would not hesitate to recommend her services."

"Rena’s organizational attention to detail and personal touch are just some of her valuable services. She has also converted our home from conventional and potentially dangerous cleaning products to natural ones that has turned our home healthier and happier (something about those essential oils). But what really sets Rena apart is her dedication and care for her clients. This was put on full display as Covid-19 hit…Rena sourced reliable PPE and other products to make managing the fear of a pandemic easier and safer."
