Is Fit PT right for me?

If you struggle with the health of your physical body, including movement difficulties, pain, discomfort, poor posture, muscle weakness, or chronic conditions that limit your ability to be active in your daily life, then we can help you!

What's the story behind Fit PT?

What's the story behind Fit PT?

Fit PT was founded in 2015 by a mother daughter duo, Diane Klos and Kaitlin Haider. These ladies saw an opportunity to take the healthcare experience to the next level by merging together their physical therapy expertise, multiple fitness certifications, and their passion for holistic health and wellness.

Fit PT provides a more personalized, well rounded care experience than the traditional physical therapy model. You aren’t limited in your care by strict insurance plans or by busy corporate hospital systems. Putting YOU in charge of your health journey creates better outcomes, success rates, and happiness!

When working with their clients, Kaitlin and Diane wear a multitude of hats...physical therapist, fitness instructor and wellness coach. These female founders work together to keep the Fit PT visionary alive & thriving! You can find Dr. Kaitlin Haider, PT, DPT at the Fit PT location in Hudson, WI and Diane Klos, MS, PT at Dynamic Performance and Therapy in Onalaska, WI.

Do you accept insurance?

Do you accept my insurance?

Fit PT is a self-pay health & wellness practice, meaning that you as the client directly exchange payment for service. Differing from a traditional, in network insurance based model, we emphasize quality care vs. quantity care. As a Fit PT client, you are given the flexibility to choose exactly what type of care you would like to receive, including how much and how often.

We offer a variety of service options and packages, allowing you to choose your own adventure! You know exactly what you are paying for up front and will never receive a surprise medical bill in the mail. We accept all major payment methods including, cash, check, credit/debit card, HSA/FSA card. If you would like to submit your physical therapy sessions to insurance for possible out of network reimbursement, we will provide you with an invoice, called a Superbill, that you can personally submit to your insurance provider. If so, please let us know at the time of your first physical therapy visit. If you have specific questions, please contact our office to learn more.

What can I expect during my first physical therapy visit?

What can I expect during my initial evaluation?

All new physical therapy clients will start with an initial evaluation. You will sit down with your provider and discuss your medical history, current concerns, and personal goals for your body. You will then be led through a thorough movement assessment to give your provider a better understanding of what your body is currently doing well and what it may need work on to improve your body’s function. This is simply a starting point and offers your provider very helpful information. You will then receive any necessary hands on body work, guided exercise, education and coaching strategies. Your experience will be completely individualized and catered to meet your personal needs and goals! We recommend wearing fitness clothing or something comfortable to move in. Indoor fitness shoes may also be helpful to bring with you.

Dr. Kaitlin is a true professional with an expertise that is unmatched. I am so grateful for her and her practice!”

I’m so excited to strengthen muscles and to get better control of my body! ”
