If you're looking for an integrative or holistic approach to your health and want to test, not guess, then implement interventions specific to the deeply rooted dysfunction, then you are in the right place. I offer 2 packages, and with either package I work with adult patients via telehealth who want to explore root causes of their health related pain points and either partially or fully resolve (when feasible), not just symptom suppression only care.

I specialize in "connecting the dots" of your health concerns (for adult males or females) via utilizing advanced functional lab testing, precision nutrition, targeted supplementation, and out-of-the-box wellness strategies to help you address the dysfunction and get it functional and feeling your best. You can learn more about working together here: About page.

I don’t offer free discovery calls, which are not customary when providers accept insurance. I do however offer an optional paid 30 minute call if you would prefer to talk to me 1-1 before booking a package.

If looking for more information, I recommend exploring:
• This FAQ page
• My 1:1 Care Page to learn about my process and the 2 packages I offer
• My About page
• My blog and podcast pages for info on my care philosophy

I offer a cash pay package for those with out of network plans. If you have in-network insurance that I accept, your time in appointments is likely covered (check out my insurance page for details on verifying your benefits for BCBS, Aetna, or UHC PPO plans). It is rare to find as Insurance Accepting Functional Medicine Aligned Practices. Many are thrilled to hear about my Concierge-Insurance Hybrid Package; this is kinda like what it sound like: a package that blends concierge services for a comparatively low fee (able to HIPAA secure text me directly between appointments, you are not a number here) and appointments still billed to your insurance, which is typically covered 100%. If you have specific questions you want to discuss via phone call, please book a 30 minute strategy call or continue to check out the website as lots of information is provided here so you can get answers in realtime.

Welcome! It is easy and all online to avoid the game of phone tag since I am in appointments all day. Click here to book a one of two package. I don't offer a la carte sessions as improving your health won’t happen in one or two appointments, and I strive to help you see a significant transformation over time. Functional medicine aligned care is very detailed oriented and a process; success stories happen when working together over time and I am committed to helping patients meet their goals.

Once you have picked 1 of 2 packages and scheduled to first appointment date/time, you’ll get a welcome email that walks you through activating your (required) HIPAA secure patient account on Practice Better, the patient portal I utilize for your records, for scheduling, for video visits, and for messaging and correspondence.

From there, you can manage your appointments, paperwork, and upload labs that have already been done, if applicable.

Please note: As a solo practitioner with no admin support, I don’t schedule appointments over the phone as I am in consults all day long. All new and follow up appointments are offered via telehealth or telephonically and must be booked online through my HIPAA-secure patient portal and scheduling system. It’s the only way to schedule with me, but fast and super convenient.

Per licensure laws, I can only see patients located in: AZ, CA (CA law requires physician referral) CO, CT, IL, IN, MA, MI, NY, TX, UT, VA, WA, WV, WI, WY at the time of your appointment.

You must be located in one of the above states during your appointment time.

*Note, licensure laws are based on where the patient is located at the time of service, not necessarily where they reside. If you aren't regularly within one of these states, try one of my online programs which licensure laws don't apply as it is general education and not 1-1 consulting.

It’s the best of both worlds and gaining popularity in the Functional Medicine aligned world. It is a blend of paid concierge services and time in consult is still billed to insurance. Providers can take on less patients, you are "not just a number" and you get more time, attention and access for care. Longer appointment times (still billed to insurance) can then be offered so you are not near as rushed compared to conventional care offices. Your comparatively low (relative to other concierge functional medicine aligned practices) paid concierge fee gets you frequent access to me through HIPAA secure messaging, more & longer appointment times scheduling, and optional personalized services like custom meal planning.

This hybrid model allows me to provide the deeper, higher-touch functional health care that the traditional insurance model alone doesn't allow for (10 minute appointments and generic advice like "eat more plants"). Traditional insurance accepting practices force providers to see 30-50 patients a day to stay financially viable, making visits short (which can't and won't help you as much).I am happy to offer Concierge-Insurance Hybrid Care as patients get better, longer, more thorough care which is ideal in the detail oriented world of holistic, functional medicine aligned care.

You’ll get ongoing support beyond your sessions, because the work we do goes deep. This isn’t surface-level advice like “drink more water,” “you’re probably just stressed,” or the classic “just eat less and move more.” We go far beyond that, and real progress requires real support.

Patients who book 6-month Concierge-Insurance Hybrid Packages will receive:

• Access to book more frequent and longer sessions with a highly skilled integrative practitioner
• Unlimited HIPAA-secure messaging between appointments
• Personalized meal plans upon request and not feeling like a number here

You'll get a confirmation email with instructions to activate your HIPAA secure Practice Better patient portal. The system will also automate your new patient paperwork before the first appointment. You can upload any labs or documents you want me to review with you during your first appointment as part of your assessment and I do appreciate having context of previous labs, medical history, etc.

All appointments are virtual or telephonic and done through Practice Better, a secure, HIPAA-compliant video platform.

Simply log into your account, click the video icon next to your appointment, and you're in. If technology is not working smoothly for whatever reason (poor wifi, browser update needed, volume settings not working) I will call you at the listed phone number. Appointment times are approximate and visits starting within 15 minutes of the scheduled time is considered an excellent time metric in a very busy insurance accepting practice. Remember healthcare workers are humans taking care of humans, not robots taking care of robots. I do my absolute best to stay on time, but please anticipate a few minute wait as I am likely finishing up with the prior patient and "I have more quick question" stacks up all day long. Thank you in advance for being kind to busy healthcare workers.

A nice deep dive! We’ll review your health history in detail, discuss your symptoms, your pain points, your needs, what testing you desire, your short and long term goals, and create an initial personalized care plan that is sent to you in writing same day outling our action steps. Depending on your needs, I will likely recommend advanced functional testing (like bloodwork, stool, or urine tests). You’ll receive your care plan, lab orders and any resources we discuss via your Practice Better portal. Over time we monitor data, your progress and pivot as needed with our focus on helping you meet your goals.

Yes! I’m actually known for advanced functional testing and interpretation, but not overtesting - the right testing we need depending upon your situation. I test when the data will/could change our care plan. I use third-party labs that offer cash-pay testing for a more in-depth view of your health.

Most patients invest between $500–$2,500 for initial and follow up testing, depending on their needs and goals. While that may feel like an investment, this kind of testing often saves money in the long run with fewer prescriptions, fewer copays, less frustration, and actually getting to the root of the problem.

Labs can be paid using HSA/FSA cards and often provide data that conventional lab work doesn’t.**Insurance companies currently are not functional medicine/holistic care aligned and they overall choose to pay for disease management screening and management only - which is important but typically not enough for those in the pursuit of wellness and optimal health. Most insurers do not cover wellness or functional strategies; Katie does not agree with their decisions but is the reality she alone cannot change. If you want functional testing for the betterment of your health and wellness, there will be out of pocket costs until the system decides to improve and catch up with functional medicine and not be discriminatory to types of care outside of the narrow minded lens that is allopathic only medicine.

Already have labs? Great. I’ll review anything you upload with you during your appointments, including past tests ordered by other providers. I am sought out for my expertise in interpreting functional testing often a second or 10th opinion for patients given over a decade of experience with interpreting labs and I order hundreds of tests for patients each month. #testdontguess. Nutrition related tests can independently be ordered by a Registered Dietitian and this in our scope of practice.

Absolutely. Healing is a process, and ongoing care makes a difference. I typically recommend at least 10 sessions over 6 months. You can book 30 or 60-minute follow-ups, and I suggest pre-booking to secure the times you want.

Log in to Practice Better to schedule, reschedule, or cancel. I don’t handle booking via text or social media for legal, privacy, and security reasons.

Yes! I’m in-network with Aetna PPO, Blue Cross Blue Shield PPO/Anthem, and United Healthcare/UMR. I submit claims on your behalf for consults, but you must call your insurer before booking your package to self-verify your nutrition benefits.

Use the free Insurance Coverage Checklist to guide that call and upload a screenshot to your patient portal. Dietitians can submit claims to insurance on a patient's behalf using "z" ICD-10 codes without physician documentation. And we commonly put z71.3 plus z68.28 (using a BMI code for example)and for most insurances I accept, that is covered and run under "preventative benefits." If no preventative coverage is on their plan with those ICD-10 codes, I can also submit a claim to be run through medical benefits but I need proof of a medical ICD-10 code via a referral showing the diagnosis code, chart notes showing diagnosis codes, or an after visit summary showing physician/PA/NP documentation of a diagnosis such as high cholesterol, prediabetes, IBS, celiac disease, etc as examples. Follow the complimentary benefits verification form to see if you have preventative and/or medical coverage of the service I provide which is essentially called "medical nutrition therapy." Once you are a patient and have booked your package and activated your patient portal, you can upload and attach these documents if they are in your possession or you can have your Doctor's office fax to me at 630-345-8638. I need them before our first appointment IF you only have coverage for medical codes. I don't have to have these records if you learn that z71.3 is a covered ICD-10 code.)

Out-of-network? Or your plan doesn’t have nutrition benefits? I offer cash-pay packages that can be financed or paid with HSA/FSA cards.

After each session, I’ll submit a claim to your insurer. If they only partially cover it or deny it as deemed by the EOB (explanation of benefits I receive from your insurer), I’ll send you an invoice. You can pay through Practice Better within 15 days or set up a payment plan within 15 days or the card on file is charged per the required signed financial agreement paperwork that automates with each booked appointment as a reminder.

If your insurance ultimately doesn’t pay, the remaining balance is your responsibility within 15 days of the invoice being sent, or a payment plan set up within 15 days of the invoice being sent or the card on file is charged.

In the HIPAA secure and protected patient portal, a card on file is required for all patients for the following ***potential*** scenarios below. Your card will never be charged if the below scenarios do no apply. It will only be charged as deemed below::
• 1) If your health insurance requires a co-pay, co-insurance, a deductible be met first, or any out-of-pocket expense that is not covered. After the explanation of benefits (EOB) is received from your health insurance for the claim submitted for rendered nutrition services, an invoice will be sent if you have any out of pocket expense that was not covered by your health insurance plan. I do not take any monies up front for in network plans for consult time when a patient authorizes a claim sent to his or her insurance. I wait to see the break down of the EOB before an invoice is issued if there is an out of pocket expense. If there is an out of pocket expense per the EOB, an invoice will be sent and that can either be paid within 15 days or a payment plan set up within 15 days. If the invoice is not paid in 15 days or a payment plan is not set up, then the card on file will be charged the full amount invoiced.
• 2) In the event of a outright denial from the patient's health insurance: if the patient would like a claim to be resubmitted, it is the patient's responsibility to call the health insurance company to inquire about details of what should go on the resubmission claim. Please notify me via the patient portal if you would like to try a claim resubmission. This must happen before 15 days have passed from the date of receiving your claim #/invoice sent via the patient portal. Your card will not be charged while we resubmit and await insurance's appeal decision. If the claim still comes back denied or not paid in full by your insurance, you will re-receive the invoice and have 15 days from this invoice to pay or set up payment plan before your card on file is charged the full amount invoiced.)
• 3) You choose a package or service that requires out-of-pocket payment 4) If you cancel or reschedule the appointment within 24 hours of the scheduled time, there is strict automatic $150 dollar fee. Also if you "no show," there is a strict automatic $150 dollar cancellation fee and your card on file will be charged. (If I have to cancel on you for an emergency, you will not be charged). This is a "keep the lights on" fee as no shows and late reschedules financially harm small businesses. Please be respectful of my time and the time of other patients who want to get in sooner. Refund Policy for Non Insurance Covered Portion of Services if/when applicable: It is my intention for you to be satisfied with dietitian services. That said, because of the extensive time, effort, preparation, legal fees, website fees, patient portal fees, insurance claim submission fees, continuing education requirements, business licenses, meal planning software, malpractice insurance, & other costs and care that goes into creating and/or providing services, no refunds will be provided for your payment of rendered services in the event insurance does not cover in full. Unless otherwise provided by law, you acknowledge that all sales are final and no refunds will be given for any portion of your payment for services rendered. No Charge Backs with Your Credit Card Company Clause: Patients agree via new patient documents (available during onboarding scheduling) that they will not issue a chargeback for any payment made as the patient is made fully aware of the Refund Policy and voluntarily consenting to it. Should a patient attempt to issue a chargeback with their credit card company or bank, they will still remain responsible for payment in full for any rendered dietitian services and collection agency services will be accessed and Attorney involvement by Dietetics with Driessens LLC when lawful. Thank you for understanding.

It depends. Most PPO plans don’t require one, but some states (like California law) do. If needed, have your doctor fax the referral to 630-345-8638.

Functional care is time-intensive, data-driven, and unfortunately not fully supported by insurance systems.

Always remember: what’s best for insurance companies (which are for-profit businesses) isn’t always what’s best for you.

Functional healthcare works. There’s a reason so many people seek it out and are willing to pay out of pocket for much deeper functional health assessments and then health optimization interventions. I’m here to guide you through it and help you create your own success story. I pride myself in providing high quality compassionate care that is holistically minded. I encourage you to check out my Google Page for testimonials if you still aren't sure about booking.
