I Have Multiple Sclerosis - How I Got it Back Into Remission

To anyone in need of a health and fitness makeover, what are you waiting for?

Okay, I waited. Why? Because I didn’t realize how bad off I was.

My physical condition and situation is a little different than most everyone else’s because I have Multiple Sclerosis. Sure, I was overweight, like a lot of other people.…

How I Overcame Drug Addiction

Dear Brian,

Who would have ever guessed that the training program I fought so much in the beginning would turn out to, not only save, but it would return my life back to me. Coming from a life time of drug addiction, I had grown accustomed to spending millions of dollars on rehab programs, physiologist and other medical professionals and treatments to survive day to day.…

I Lost Three Inches on my Waist

Dear Brian,

I have to tell you how much you have rocked my world!

Over the past two years, I dropped about 20 pounds on my own, but I wasn’t happy with how I looked. I wasn’t “fat”, but I still had a gut and my body didn’t have any definition.…

Change Our Lifestyle & Live a Healthier Life

Dear Brian

We wanted to take the opportunity to share our experiences with you after completing the 60 – day executive program. We are not your “typical” members, we were neither elite athletes desiring to gain a more competitive edge nor do we have medical problems, hoping to lower our blood pressure or reduce the amount of medication we were on.…

I Can Sleep on My Back Without Pain
Dear Brian,

Thank you so much for working with me and all the challenges I have presented you.

Your enthusiasm and encouragement was much appreciated and needed during the “rehab” portion of my training. Initially, I was discouraged as I thought all the training we did prior to my back incident was wasted.…

To Whom It May Concern:

I Was Able to Lose 12 Pounds of Fat in 60 Days

Dear Theiss

I am very pleased to be writing a letter of recommendation for TheissCare. I have plenty of reasons why I would highly recommend TheissCare to anyone.

For someone like me who is 5’2″ and weighed 129 pounds it was very difficult to get in shape and lose the last 15 pounds.…

Training Program Built for the Business Professional
Dear Mr. Theiss:

Being in my mid to late forties, feeling sluggish, weak and overweight, I decided to search for a training program that would benefit me on my terms. I felt I needed individualized attention, someone to work out with me, to push me. If there were a diet offered, that would be a plus.…

I Lost 17 Pounds in a Month and 60 Inches

Dear Brian,

How can I begin say “thanks” for all you have done for me? I have been overweight almost all of my life and the word “exercise” was my four letter word. I was apprehensive about starting your training program believing there was no way I could possibly succeed. I imagined the program to be too hard for me to do.…

How do you THANK someone who just saved your life?

Dear Brian,

How do you THANK someone who just saved your life?? Mere words do not seem enough. I cannot begin to express how wonderful it was to meet you in October in Minnesota through Bill. From the moment that we were introduced I knew that I had to meet with you at your facility.…

I Was Capable of Doing Many Things

Dear Brian,

As long as it has taken for me to get this letter to you, I hope you know it is not because I am unhappy with the results of my training; quite the contrary. It is simply procrastination…. nothing else.

I do want you to know that I learned a lot about myself in many ways during the training sessions; some of it was not very flattering, but mostly it was wonderful.…

I Look Forward to a Fit and Healthy Life

Dear Brian,

RESULTS – that’s what I have achieved in your cutting-edge training program!

And, in dramatic fashion, I was able to FEEL my increased energy and strength.…


Dear Brian,

Physical Rehabilitation for Our Chronic Conditions

To Whom It May Concern:

Living a Much Healthier Lifestyle Saved My Life

Dear Brian

The impact of the Theiss training program on my life is so profound and huge, I am amazed each and every day. There aren’t enough words, time or money to express my gratitude to you for saving my life and giving me the tools to live a much healthier lifestyle.…

My Life Had Already Started to Change

Dear Brian,

I had never lifted weights or used weight machines or even exercised on a treadmill before I met you. I hadn’t run for 30 years, and when I ran I hated it. I never got that euphoric feeling everyone talked about and craved. In fact I really never exercised before except for walking – which I did a lot of.…

Fitness Training Made My Heart Strong

Dear Brian,

When I began training at your gym in May little did I think that less than a year later, I would be diagnosed with immediate grade infiltrating lobular carcinoma…breast cancer. I had a bilateral mastectomy and removal of all lymph nodes on the affected side. Cancer was present in two of the nodes and was also found in the surrounding tissue.…

Thanks for Helping Us Change Our Lifestyle
Dear Brian

When we first met you, we expressed concern that our unhealthy lifestyle was interfering with our ability to keep up with our four year old son. As a middle-aged executive with a high stress job, Alan was concerned he was too out of shape to ever hope to play baseball with him.…

Kicking My Once 'Low Butt' Into High Gear

Dear Brian

I know this letter is long over due and I ask that you please accept my sincere apologies for the lengthy delay. In the same breath, please know it doesn’t lessen my passion for wanting to write it.

the benefits of a healthy diet and exercise plan

Dear Brian,

I wanted to take time to let you know how you and your staff have helped to permanently change my life. After my personal health consultation, you gave me a lot to think about as well as a stack of forms to fill out. The forms were overwhelming, at first, but yet I understood the importance of having the proper medical and physical information in order to establish the right recommendations for my program of physical well-being and a healthy diet plan.…

Being Healthier for the Rest of My Life

Dear Brian,

I would like to take this opportunity to express to you my deepest gratitude and appreciation for all that you and your staff have done for me. Being at TheissCare has been more than a fitness training or diet management program for me. It has truly been a life changing process.…

I Watched My Father Die From Diabetes. I Would, Too

Re: Gratitude

Dear Brian,

Thank you.

At age 54 my vision was acceptance of decline. Month by month more things going wrong with my body. The negative statistical facts of diabetes ever piling up. Long spiral down ever accelerating. I was making my self comfortable with this inevitability. I watched my father die from diabetes.…

You Could Help Me Lower My Cholesterol
Dear Brian,

I’ll never forget talking with you in February about my cholesterol problem. It’s always been a problem for me. You convinced me you could help me lower my cholesterol, when all the medications I had tried gave me nothing but side effects. Every time I had my cholesterol checked, it had gone up.…

A Lifestyle that Promotes Success, Health and Well-Being
Dear Brian,

It’s difficult to express in words the impact your online fitness program has had on my health, and overall attitude toward health and fitness.

With my extensive exposure to power lifting and strength training, I approached this training program extremely skeptical of the impact it would have on my body type.…

A Disciplined Eating and Exercise Program for Health

Dear Brian,

I wanted to commend you on the training program you designed for me. As you may remember I do a tremendous amount of travel, which makes it very difficult to be in a disciplined eating and exercise program. However, the online fitness program you set me up on after spending two dedicated weeks with you has been very rewarding.…

My Cardio-vascular Strength and Endurance Increases

Dear Steve,

Over the past eight weeks, I have been on an individualized fitness training program created and directed by Brian Theiss in Westlake Village. The enclosed copy of my letter to him, which I wrote upon completing my 6 1/2-week program, gives you a good sense of what he helped me to achieve.…

I am a firefighter diagnosed with brain cancer

Dear Brian Theiss,

I would like to thank you and your staff for all your hard work. I am a firefighter/paramedic who was diagnosed with brain cancer. After a year and a half of chemotherapy, my body was beat up and out of shape. After working with your team, I was able to return to full firefighting duty.…

The Beginning of a Lasting Fitness Change in My Life

Dear Brian,

I didn’t need or have the money for another “gym membership”! And I had hired Personal Trainers in the past… with poor, short-term results. So when I wandered onto your doorstep 11 months ago, I was very skeptical and resistant. During my life, I’ve heard just about every pitch imaginable.…
