I saw Ogbonnaya! So happy that I did. My calves were feeling tight even though I workout & stretch. He check them out, asked the right questions, assessed & began the work. I did exercises, corrective movements & received dry needling which helped. Thorough & worth the investment! I highly recommend 😀

My experience at CLIENTEL3 has been fantastic. I've been coming here for over a year now as someone who had experience with exercise and fitness as a college track athlete but wasn't able to keep up the discipline as an adult, especially after suffering 2 knee injuries. I was apprehensive and nervous at first to get back into things after 15+ years off but the trainers at CLIENTEL3 have been amazing - I've been working with Aidan and Grayson who have really been superb at helping me maintain my fitness goals. Furthermore, what has made CLIENTEL3 truly perfect has been the the physical therapy provided by Ogbonnaya. After having been inactive for so long, I realized that my old knee injuries were quickly becoming a road block to my progress. Ogbo has taken me from thinking that I'll be doomed to a lifetime of knee pain to being able to do more than I even thought possible. He's very skilled and goes above and beyond to adapt to my needs from session to session. Highly, highly recommend CLIENTEL3!!

I had a great experience at this PT clinic. Ogbonnaya helped me recover from an adductor injury and got me ready for my half marathon, which I ended up beating my goal in. Grayson and Aidan were also super helpful early on and gave me really clear, informative guidance. Highly recommend this team!

I’ve been coming to this gym for about a year now, and it has completely transformed how I feel about fitness. Grayson has been my main personal trainer, and he’s genuinely exceptional — consistently prepared, incredibly knowledgeable, and always able to strike that perfect balance between pushing me and supporting me. He pays attention to the details, adjusts sessions based on how I’m feeling that day, and explains the “why” behind every movement. Training with him has made me stronger, more confident, and way more consistent with my routine than I ever thought I’d be. I’ve also had a few sessions with Chi and Aidan, and each of them brings something unique to the table. Chi, who’s also the owner, deserves a special mention. He’s incredibly kind, patient, and genuinely cares about every person who walks in. You can feel that the community and atmosphere here come directly from his leadership and personality. The gym is clean, welcoming, and never overcrowded. Workouts are tailored, effective, and actually enjoyable. After a year here, I genuinely look forward to training and feel better than ever. Couldn’t recommend this place more — if you’re looking for real personal training with trainers who truly care, this is the spot

I’ve been doing physical therapy with Ogbonnaya for over six months now and have nothing but great things to say. I’m prone to pulling my back a few times a year, and Ogbonnaya has been working with me to strengthen my body to prevent future issues. He explains what each exercise is doing and provides video instructions so that I can keep doing them at home. I now feel so much more confident in my form. I can be lazy when it comes to picking which weights to use and Ogbonnaya pushes me to use weights that he knows my body can handle. I’d highly recommend working with him!

I am in my mid 60s and very focused on keeping myself in shape so I can enjoy this chapter of my life. The team at Clientel3 has developed a program that works on my weaknesses and maintains my strengths. I highly recommend them to anyone looking to improve their quality of life.
