Medical Services

HealthWorks is more than just a doctor's office!

As your family’s medical home, HealthWorks is a place you’ll always feel welcome, seen, and cared for.

To make health care affordable, we offer a sliding scale fee structure for our income-eligible patients. We also accept most insurance.

Getting to know you creates a unique opportunity for us to work together and connect you with resources (including community partners and/or our care and case management services) to improve your quality of life. 

Have you been diagnosed with, or been told you’re at high risk for, a chronic illness or disease process such as diabetes, hypertension, or COPD?

Ask your provider about connecting with care management, a health and wellness program for HealthWorks patients who are invested in improving their quality of life and motivated to achieve personal health goals. 

Walking with you on your journey, your care manager will collaborate with your physician to provide: 

  • Individualized diet and exercise recommendations to help you alleviate symptoms and improve your quality of life
  • Support and encouragement at your regular one-on-one meetings, including setting and/or reviewing your goals and celebrating your progress
  • Assistance with food shopping and meal prep (including choosing recipes, making a grocery list, and teaching you cooking skills at our in-house kitchen area) 

Wherever you are in your journey, we're here for you.

When you fill out your patient paperwork, you’ll have an opportunity to share information about your current living situation (including access to utilities, clothing, food, transportation, etc.), finances, insurance, and mental health. 

Based on your answers, our Eligibility and Case Management team will meet you right where you are and work with you to find the best local resources to meet your needs. Additionally, your case manager will stay with you all the way through your journey, providing ongoing support and checking in regularly to ensure you have what you need.

Success stories

Quotation Marks Icon

I was one of the earliest patients at HealthWorks. In 2005, I was sent here by a pain specialist, and my doctor told me that if I didn’t change the medication I was on, I would die soon. Since my HealthWorks doctor offered to handle my pain management, my health has improved—and I’m still alive today.

-Carl S.

Overall, I’m very pleased with the service and care I receive from HealthWorks. They have always been there for me, they are caring and understanding, and my provider really listens to me.
