About Us

Evolve's Evolution

The idea for our treatment center started out as a tiny seed in 2009 when Brenda Velissaris noticed a huge gap in the levels of care offered to people struggling with an eating disorder in the Fox Valley. Though the seed was planted it did not grow into much until Brenda and Kate Yonke met at a community meeting in 2013. The two introduced themselves to each other and within minutes the seed began to germinate and Evolve began to well, evolve.  In less than a year, Kate and Brenda created a center for eating disorders that fills in the treatment gap here in the Fox Valley.  In the beginning, Kate provided the nutritional and dietetic knowledge while Brenda provided the mental health/therapeutic knowledge.  Since then Evolve has continued growing into a state licensed practice that includes five therapists and three dietitians providing individualized care to those who are struggling with eating disorders.

Evolve offers comprehensive individual, family and group therapy, individual nutritional counseling, and a variety of experiential therapies by our experienced team of counselors and dietitians. We also offer Intensive Outpatient Programs (IOP) for adolescents and adults who require more support to individuals and their families than outpatient alone can offer. We believe that everyone can have a healthy relationship with food, themselves and others and we’re here to help you plant the seed to recovery.

Special note about dietitian coverage:

An eating disorder program from Saris Counseling LLC

We make every effort to work with your insurance carrier for dietitian coverage. However, each insurance carrier has a separate set of rules and policies that govern coverage it can be difficult to remember and manage all this information from different sources.  We will contact your insurance provider to verify coverage however, we are offering you a self-service guide to use when verifying your insurance coverage to help you better understand the coverage for dietitian services.

  • Evolve is a program within Saris Counseling LLC so when contacting your insurance carrier you are asking for coverage with Saris Counseling.
  • Some insurance carriers will ask for information about Saris Counseling such as Tax ID number, NPI number or billing codes. Here is that information.
    • Tax ID: 263443205
    • NPI number: Saris Counseling LLC 1700018389
    • Dietitian billing codes: 97803 and 97802
    • Diagnosis we bill for: F5000, F5001, F5002, F502, F509 and Z713
  • When you contact your insurance carrier please confirm that Saris Counseling is an in-network provider. We are in-network with all major insurance carriers however there are some market place plans that we are NOT in network for so it is essential to make sure we are in-network.
  • Ask the customer service representative if there is DIETITITAN COVERAGE FOR EATING DISORDERS within your plan. It is important to ask for this specific coverage as some insurance carriers offer dietitian coverage but only for diabetes or cardiac care.
  • If there is not coverage for dietitian services for eating disorders we offer out of pocket rates or ask your insurance carrier about a gap exception or gap request. A gap exception or gap request is essentially requesting the insurance to cover a service that is not covered within your plan. These are based on need. Gap exceptions/Gap requests are requested by the insurance holder not the service provider, however information from the service provider may be needed such as progress notes or medical data.

If there is coverage for dietitian services for eating disorders then you will need to find out if there is a limit to how many sessions you have per calendar year, if there is a co-payment for each visit and/or if you have a deductible for the calendar year.

If you have questions please reach out to us, we would be glad to assist you in any way we can.
