Who we are and why we love helping you

Dr. Nathaniel Hoover, PT, DPT, OCS - Clinic Director

Dr.  Hoover is a Wisconsin native practicing since May  2012

Why did you want to be a physical therapist?

After sustaining a fracture of my low back when I was 16 years old when snowboarding, I personally learned the great benefits of physical therapy. My back injury motivated me at a young age to pursue my dream of helping patients regain their function and decrease their pain to participate in what they enjoy.

What can the patient expect when they have you as a doctor?
“My patients can expect a detail-oriented, caring approach to their care. I take great pride in understanding what my patient is having trouble completing and work with them to meet personalized goals. I value education, manual therapy and exercise. I feel that if a patient can understand and learn the reason for their pain or dysfunction, they will be successful in changing it.”

What is the most important factor in a doctor-patient relationship and why?
Communication. Clinicians need to understand what a patient is going through to be able to help them most effectively. Sound communication allows for empathy, appropriate intervention, education and ultimately goal attainment.

Year you became a physical therapist?  2020

Why did you want to be a physical therapist? 

I always knew that I wanted to make a difference and brighten the days of people, but I never knew how. This is when I felt called to the PT profession. I love to be able to help a patient who comes in with pain or issues and have them leave the clinic feeling like they have been heard, understood and have a plan that will help them get back to what they love to do. People and their bodies are stronger than they know. Giving them the right tools to better their movement can aid in their human experience, and I feel incredibly honored to walk side by side with patients through this journey. 


Undergraduate – University of Wisconsin- Superior

Graduate- South College, Knoxville, TN

Areas of special interest: Pelvic Health, CrossFit athletes, on-site injury prevention, work conditioning.

What can the patient expect when they have you as a doctor

Every patient can expect to be treated with sound listening and understanding of their personal story. I always say “patients know their body the best.” Listening, communicating, and guiding patients towards their own personal solution and treatment plan.

What is the most important factor in a doctor-patient relationship and why? 

Open communication, comfort, compassion, and best practices for results.  The doctor-patient bond is important for patients to feel comfortable sharing concerns, wins, and defeats as well as empowered as a patient to embark on the healing journey.

“Dr. Sara figured out what my issues were, got me working on the exercised for them and I am now back to being able to move like I had before with no pain.”
John Puhr

“We are so impressed with Sarah!”
Olivia Bartels

“My Dr. listens very well and helps me understand everything she is having me do and how it impacts my healing.”

Dr. Brenna Meyer PT, DPT

Dr. Brenna Meyer

Year you became a physical therapist?  2014

Why did you want to be a physical therapist? 

I always knew I wanted to work in health care, but wasn’t sure what avenue to take. Then after a minor injury and going through my own physical therapy I knew it was something I wanted to pursue. I enjoy helping others to become or stay active and use movement as medicine. I have also been interested in Women’s Health since PT school but have a new appreciation for the need for this type of care after going through 3 pregnancies, deliveries and the recovery that comes after. 


Undergraduate – University of Wisconsin- Madison

Graduate- University of Wisconsin- Madison

Areas of special interest: Pelvic Health, pregnancy and postpartum recovery, orthopedics and spine therapy.

What can the patient expect when they have you as a doctor? 

Collaboration. We work together to identify and meet your goals. 

What is the most important factor in a doctor-patient relationship and why? 

Communication is key to a positive doctor-patient relationship. Effective communication goes beyond asking questions and thinking I heard what you have said and what you have heard. Patients have a fear of what to expect when participating in physical therapy. Communication helps reduce fear, increase ownership of their recovery and makes physical therapy safe and goal worthy.

Dr. Joy has been practicing Physical Therapy since May 2016 and specializes in treating older adults and patients with neurologic conditions.  She is licensed in Illinois and Wisconsin.

Why did you want to be a physical therapist?

Physical Therapy (PT) is my second career.  After being in the mortgage industry for 10 years, I decided it was time to start helping people move better instead of helping them put more money in their pockets.  At the time, both of my grandfathers were ill which impacted my decision to enter the healthcare sector.  More specifically PT because I get to spend quite a bit of time really getting to know my patients, allowing me to better understand their motivators and goals.

I fell in love with learning about the body in a Human Anatomy class in high school. While participating in many sports, I enjoyed learning why we move the way we do and how to correct improper movements in the body.

Listening to the patient and clearly communicating a plan has made a huge impact on results. You should feel comfortable working on the plan and working with me.  Trusting your therapist is imperative as well as making the process fun instead of work.

Communication! Being open and honest with each other is important in meeting 100% of your goals.

“Tiffany and Optimal helped me move around again without pain.  Tiffany was very knowledgeable.” - Bill Blaska

“The staff here are amazing. They are professional, knowledgeable, and encouraging every step of the way. After thoroughly assessing my individual needs, a therapy plan was developed that supported strengthening and returning me to my optimal health. The collaboration is throughout the entire recovery process with constant feedback and communication. They listen, encourage, support, and work with you every step of the way. Another great option that you don't find everywhere is the exercise pool. It's another level of therapy that isn't offered everywhere and it's so wonderful.

I started therapy before my surgery. Dr. Nate and Tiffany helped with strengthening and prepared me for what to expect after my surgery. I am thoroughly convinced that I am walking better because of the therapy plan that Dr. Nate and Tiffany worked with me on both before and after my surgery.

I can't recommend Optimal Physical Therapy enough. I am thankful that I found them and can't imagine going anywhere else!” - Vicki Fitzsimmons

Mara Martin, PTA

Mara Martin, PTA

Mara grew up in central Wisconsin, moved to Madison to attend college in 2011. Mara joined Optimal in 2021 and provides physical therapy treatment at The Ranch in Marshall under Optimal Physical Therapy.  She also operates a gym in Marshall called The Ranch Training Center with her boyfriend Max. 

Why did you want to be a physical therapist assistant?

In high school, I realized from my anatomy & physiology class that I was fascinated by the human body. I researched potential majors and landed on studying Kinesiology in college. I was offered many unique opportunities working with different populations of people throughout the next few years, such as in-home caregiving, volunteering with UW-Madison’s Adapted Fitness program, becoming a personal trainer, and leading multiple programs for MSCR’s Adapted Recreational Department. From these experiences, I knew I wanted to continue working with people in a healthcare setting and was most interested in the profession of physical therapy. I decided to become a PTA because it was more cost-effective for me and I was able to stay in the Madison area, where I had been building invaluable relationships for the past several years.

Why Marshall?

Marshall is a community that has been lacking in both fitness and physical therapy resources. The Ranch had already established many connections in the neighboring town of Waterloo, so we decided to expand our small personal training studio into a fully operating gym in late 2020. We knew we could offer more services with the size of our new facility, so we reached out to Optimal about expanding its physical therapy services through our gym in Marshall.

  • Injury Prevention Specialist Certification
  • American Heart Association Heartsaver CPR/AED Certification

What can the patient expect when they have you as a therapist?

Listening to my patients because there is often much more to the puzzle underneath the surface. Being stubborn, solutions for your physical limitations can be found in many ways.

What is the most important factor in a therapist-patient relationship and why?

Trust. If you can’t trust your provider with your health, you’re not getting the care you deserve.


  • Associations: Marshall Area Business Association and the Lake Mills Chamber of Commerce.
  • Memberships: American Physical Therapy Association—Wisconsin 
  • Volunteer: Assistant coach for The Ranch Training Center’s Powerlifting team

STAYING FIT: I enjoy lifting weights, biking, and hiking.

FUN TIME: Exploring new restaurants, traveling, and spending time with my malamute, Arya.

Favorite treatment and Why?

I love incorporating manual therapy techniques into my practice, particularly soft-tissue mobilization (massage). The human touch is so important for both its physical and emotional benefits, such as establishing trust with a person.


"Mara is not only my PTA with Optimal, but also my (Personal) Trainer at the Ranch Training Center, helping me to overcome some physical issues through treatment and strength. She has the ability and techniques to not only address the aches and pains that come with life, but also continue to build my strength and agility to be able to help me see my personal health goals become a reality.  Her understanding of how the body works is amazing. I ask a lot of questions and she has great answers.  She listens, she cares, and she strives to make me strong and healthy.” - Lynn P.

"Optimal Physical Therapy helped me by correcting a bicep issue that was holding back my strength gains, Mara is the best!!" - Patrick Edge

“When I decided to have my knee replacement, I knew I would have a ton of PT appointments. My insurance allowed me choices where I was able to go for therapy.  I chose Optimal PT because of its location.  From the first appointment, I felt heard, valued and respected.  The pain was incredibly intense in the beginning and Dr. Nate devised an exercise routine that allowed for recovery with respect to my pain.  He pushed me gently to respect my body and still meet my own goals.  As I work with Mara PTA at The Ranch in Marshall now, she is continuing to build on what Dr. Nate started.  She has continued to encourage me as I recover.  I would highly recommend going to Optimal PT for post-op recovery!” - Rebecca Milam
