Dates of Live Course To Be Determined

Your class has helped me to better understand the how and why behind the different aspects of nutrition and lifestyle changes. It's exactly what I needed to help me move forward on my journey!

How carbohydrates affect blood sugar was the best explanation I have ever heard

Great information

Payment Information:
  1. To purchase and schedule an appointment, use the Scheduler below. You can also pay via Venmo (@Jillian-Ondreyka), which is preferred as they don't charge fees (win-win!). 
  2. Unfortunately, RDNs are not able to contract with insurances directly in Michigan (where I live). I can give you a superbill to provide to your insurance for potential reimbursement.
  3. I do accept FSA/HSA payments. 
  4. I recommend taking advantage of PayPal Credit. They offer no interest for 6 months on purchases over $99. This would provide a monthly payment plan.
