I can’t say enough good things about Zenith. After over a year of lingering adductor pain that seemed to come out of nowhere, I finally found answers and treatment here. As a semi-professional runner, lingering pain isn’t something I can afford. It throws off my form and affects every part of my training, including lifting. So I went to a doctor who thought it was iliopsoas tightness and they sent me to a PT who thought it was an adductor strain and made it worse.

Then I came to Zenith and started working with Jesse. He took the time to understand the full story and offered a completely different perspective: this wasn’t a strain or tightness but actually a nerve issue. That insight alone was a game changer. He worked on the problem during our first session, gave me daily stretches, and even made simple lifestyle suggestions that I hadn’t considered (like actually using my standing desk throughout the day).

The progress was slow and steady. After the first follow-up, I still had some discomfort, but the plan felt like it was finally targeting the root cause. Jesse introduced strength training specific to the problem area, which I was initially nervous about. After my first lift, my muscles were sore in and around the adductor area, but the pain didn’t worsen. That was the turning point for me.

After just four sessions and a few months of consistent stretching and strengthening, I’m nearly 100% better and still improving. I’m back to running and lifting with more strength, confidence, and most importantly almost no pain.”

“If you’re dealing with a nagging issue like me or an injury then I would highly recommend Zenith. It’s an investment, but for me I saw it as a long-term investment in my body’s future, and I’m glad I did because it was absolutely worth it.

Helped Me Resolve My Back Issues

I’m convinced that Mariel knows everything about the athlete’s body. Nice, intimate facility with plenty of equipment for anything you need to work on. They helped me resolve my back issues and transition into better overall mobility and strength training.

Exceptional Care from Mariel and Jesse

This is a review for Mariel and Jesse: I have had many massages with Jesse. He is methodical, receptive, and thoughtful with every massage. If you have a trouble spot he will definitely spend the time working on it but will budget his time to make sure you end up with a full body massage as well. I have never left without feeling better and that I wasn’t worth it. He is very good at getting the knots and tension out without subjecting you to abject torture. A true sports massage with the benefit of full body relaxation. The only caution I’d give is that he is in a “gym” space. If you do not mind the VERY occasional “sounds of the gym”, you will be fine. However, if you use the massage room as a means of escape into a quiet, serene, transcendent space without ANY external distraction - there may be the occasional thud of a weight. But by no means are the sounds constant. I can still find my peace. I worked with Mariel initially for my back and then my shoulder. I started by seeing Mariel for my back which started to progressively improve and during this time my shoulder flared up. I didn’t need a new referral, I didn’t feel bad about bringing it up, we seamlessly transitioned into working on both without any issue. She is a consummate professional, insightful, and knowledgeable. At the same time, she is fun, laid-back, and gives reasonable advice and adjustments to work towards your goal. I would trust her with any physical therapy ailment I have.
