From the reviews
Pedro is the best coach to have in your corner. He is sincere and genuine. He will help you reach goals you didn’t think you could reach. He is dedicated to every person he teaches and cares about helping them succeed. There’s no one else like Pedro.
I have been a student under Pedro for 2 years now, he’s very professional, always makes sure you know what’s going on. He has a want to learn that inspires me every day to go to his classes because you never know what cool move or idea he’ll spark in you for you game.
I've known and trained with Pedro for a couple of years now, honestly he was one of the main reasons I decided to sign up, after only one week I could really tell he was a great coach and he really wanted me to learn. He's been great on and off the mat.
I’ve been at sierra for 1.5 years now…. As a fighter coming from a bigger gym to a smaller gym was a bit of a transition for me. Pedro and head striking coach Tre had to have several conversations with me on what was to be expected from me as a student, athlete, and training partner!
New to muay thai? Start at Sierra MMA
Sierra MMA comes up as a beginner-friendly gym, going by their listing and members’ reviews. If you've never thrown a punch or a kick, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit to start — you get in shape by training, not before it, and coaches scale the conditioning to you. Second, you won't be thrown into sparring — reputable gyms build fundamentals (stance, footwork, and the basic strikes of the "art of eight limbs") for weeks before any contact, and sparring stays optional. Third, all levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out. Most gyms are happy to let you watch or try a class first, so reach out before you commit.
Your first muay thai class at Sierra MMA
Nervous about walking into a muay thai gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling the basics on pads and bags — not fighting. Rest whenever you need to; no one will bat an eye. What to wear: shorts or athletic wear and a t-shirt; you'll train barefoot on the mats. What to bring: water and hand wraps if you have them — many gyms lend gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves, wraps, a mouthguard, and shin guards. Sparring is optional and comes later, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.
