I've attended Southern California Welding Training and Testing Center for about 12 months and it's been one of the greatest decisions I made. I get tons of hands on training. It allows me to progress as fast as I commit to attending. Within the first few weeks I had a certificate in hand. Jesse has a wealth of knowledge teaching about various welding techniques and he explains everything easily. The location was convenient for me and I was able to secure a job in the aerospace field thanks to my teacher.

Ventura, CA   

No other school in a 100 mile radius from me could offer what Jesse at scwttc could offer. It took me about a year to complete coming in every day but it was well worth my while after earning my certificates.

I learned so much from all the courses he offers including pipe fitting trade. I would recommend SCWTTC to anyone looking into the trade school route.

Oxnard, CA   

I've welded for over 20 years. A friend recommended Southern California Welding Training and Testing Center for TIG certification. It's a private school that Jesse founded. I've been seeking TIG certification over the years going to college classes part-time because I work full-time, but I was certified after only five months at SCWTTC. Jesse's welding knowledge is well-rounded and very precise in his technique and teaching. Thanks for everything. It's totally worth it.

Oxnard, CA   

This is the best school that I learned pipe welding. It's a great school with an amazing teaching staff. Looking forward to coming back soon .

Oxnard, CA   

I enjoyed attending classes at SCWTTC very much. Jesse is an excellent welder and a patient, friendly, knowledgeable instructor. He made being there a pleasure. The school is a clean, professionally-run facility. All of the machines work correctly. I definitely recommend this school to anyone considering welding career. I'll be returning in the future for more classes.

Camarillo, CA   

I had very little experience with welding before i started but i learned everything i needed to know to go out into the field.

I highly recommend this trade school.

I'm extremely thankful for everything the school has shown me. It was an investment that my family has been benefiting alot from. I struggled alot working full time and raising my new born son while attending this trade school. It's a great starting point for anyone wanting to start a welding career.

As a student who enrolled before I even graduated high school, SCWTTC really helped me get a head start on my way out of school and in to the work force. Couldn't have spent my time any better.

I initially learned about this school through some friends. The staff was always helpful and made taking the first steps to enrollment very clear and easy. Now, in less than a year from enrollment, I couldn’t be more glad to have completed the structural program.

The different programs offered here at the school are broad and give anyone with or without previous experience the necessary skills and knowledge to land themselves in a new career. Through Jessie and some of the other instructors at the school, they’ve helped start a new career with a strong foundation about welding and the field.

With that being said, you only get out what you put in and anyone serious about enrolling should be prepared to be focused and consistent. That’s what will make the difference throughout your experience at this school.

Overall, highly recommend this school and will definitely return for further learning in the future! For anyone looking to learn or enhance their set of skills SCWTTC is the place to do it!

The school's shop is clean and organized and the staff are friendly... If you're looking for help and guidance along the welding career path then Jesse is the man you need to see... I've gotten all of my certifications through SCWTTC. I'll be coming back soon to grab some more just for fun.

Camarillo, CA   

The staff and instructors at the school are professional in both teaching the curriculum and one on one coaching. A student of SCWTTC who finishes their discipline and certification will be confident of their skills in any job setting.
The new facility is magnificent and took 2 years to build it out. The school is designed to offer courses based on your individual schedule. Flexible scheduling is beneficial for those of us working who need access to evening and weekend classes. Students progress at their own pace toward proficiency. I had to be the slowest learner in the history of the school. The instructors were patient and coached me. I am now a certified welder which is very cool.

I just graduated from my course and now have 5 certifications. I came into this school with 0 welding experience but with the help of the great teachers I am confident to say that I feel prepared to start my career as a welder.

I just finished my 2nd class at Southern California Welding Training and Testing Center. SCWTTC fully deserves five stars. Jesse is a great instructor with the right qualifications; knowledge, experience and the knack to help students understand ways of improving. The school is maintained in a clean and orderly fashion and well supplied with right equipment. I enjoy the other students. They come from a variety of backgrounds.

Port Hueneme, CA   

I really enjoy testing at Southern California Welding Training and Testing Center. Jessie Guzman is the instructor and very helpful with anything that you need. The facility is always clean with a nice good atmosphere. I would recommend this school/training facility to any one who wants to get certified or learn how to weld.

Oxnard, CA   

Attending was one of the best choices I ever made. Senior is the best at what he does and isn't afraid of teaching and sharing what he knows. It was worth every penny. Senior and his team are always helpful and flexible. I'm confident now to go out and apply everything I have learned.

I hope to work with you guys soon.

SCWTTC takes their teaching mission seriously.

I started without any welding experience and was nervous. My nervousness quickly truned into a passion and love for welding. Expect to become a great welder not just an average one and have fun doing it.

My welding skills improved more within one year at Southern California Welding Training and Testing Center than four years previously attending other schools. Jesse really knows his craft and is a great instructor.

Ojai, CA   

Drove from out of state to attend here. I feel like I learned a lot under their instruction. Great school, good work environment, very enthusiastic instructor.


After years of wanting to get into welding I finally made the jump and looked into different schools. I came across SCWTTC and was impressed by the variety of courses they provide. I started with little to no welding experience and very nervous about getting started, but after a week I was hooked and wishing I could come in everyday. Jesse made learning how to weld very easy and fun to learn. I’m extremely grateful for the time I’ve spent at SCWTTC and the people I got to know and everything I got to learn.

Thank you for everything!

I did the general class here in SCWTTC and it was really great and learned a lot of new things about welding and improving my skills.

The instructors are always helpful. I highly recommend attending here.

I had a good experience learning here. I can be slow to pick up on things sometimes but the instructors were patient with me and I made it through.

Great school & staff. All the keys to success are given to you. Great environment to learn about this trade. Really knowledgeable teachers & peers. 10/10 recommend

The instructors made it easy for me to learn at my pace and helped me when I struggled in a way I could understand. I learned how to use all the equipment and tools that are used in welding.

Thank you so much for everything that you did for me.

The instructors and staff are the best and are super knowledgeable!

I am a recent graduate of the structural program.They took me from completely unexperienced to a certified welder quickly. The instructors and staff are the best and are super knowledgeable! They went above and beyond, helping get me into the industry. I highly suggest scwttc!


I can't forget the encouragement SCWTTC has given me. I want to be the first to say that the instructor at this school helped me out so much with the honesty convincing me I could be able to be in aerospace and now i living my dreams at spacex.


Santa Paula   

Its good.

I Highly recommend attending if youre trying to learn to weld! They also administer weld tests for people who have already learned to weld and need to get certifications!

Learned to mig and tig weld here with no previous experience. Graduated with certifications in automotive welding and fabrication in 7 months.

Staff is very cool and works with your schedule and skill level. They have many machines/saws/drills that they teach you to use safely and correctly as well as a large work area and individual welding booths for each student.

Oxnard, CA   

i recommend this great school to anyone. The staff are very helpful and hands-on, they thoroughly explain everything. The shop is a very clean, organized and well-maintained environment. After completing my tuition i got all the welding certs that I needed for the job i was applying. Thanks to SCWTTC I'm now a unionized welder and making well paid.

Oxnard, CA   

I was looking for a good career in welding. SCWTTC is a great school with very nice staff.

Oxnard, CA   

Don't know what to say except I had the most fun while attending the SCWTTC here at Oxnard. Started with no knowledge regarding welding let alone the different variations of welding and its uses in everyday life. Jesse and Jr. really are the best at what they do and they will make sure to properly explain thoroughly until you get it right. The staff are amazing and you'll always will feel welcomed while you attend here!

Oxnard, CA   

I attended Southern California Welding Training and Testing Center as soon as the school opened. I've done metal work since I was a freshman in high school (2003) but was never completed any certification programs because the waiting lists were too long or other schools were too far. SCWTTC's location is perfect for any one in Ventura County. I received minimal instruction at Ventura College's welding classes and dropped from it because there were too many students. A friend referred me to Jesse G. and within the first three months I received my Advanced MIG certification. I appreciate the hands-on, one-on-one instruction and flexible hours. Work at your own pace or burn straight through and earn a certification, doing the hours and testing as fast as you can. I'm currently working towards a welding career in the Aerospace industry. Everything is to AWS standards and I've gained more skill in 6 months at Southern California Welding Training and Testing Center than all the other classes and shop work combined.

Ventura, CA   

Throughout the years I've attended several f schools in attempt to get my structural steel welding certifications. It's safe to say that SCWTTC is, hands down, the best bet for guaranteed results. I now have both my SMAW, and my Fluxcore certifications after six months with Jesse. There's no comparison, Southern California Welding Training and Testing Center is a clean shop, equipped with top-of-the-line machines. JJesse will work with you hands on to ensure that you get the attention and direction needed to pass your certification tests. If you are serious about a career in welding I definitely recommend this school.

Santa Paula, CA   

If you want professionalism, actual challenge, and consistent help as you go through your journey- this is worth looking into.

In December 2021, I started after weeks of looking at schools for my welding certifications. The school stands out enough to bring students that drive in from cities over just to experience getting taught by Jesse and now I see why. I went in with no experience, and fresh after graduating from SCWTTC I landed a job with Spacex welding.

They teach clearly and concise, and they utilize the time you’re given there from beginning to end. Things are always prepared, I had material consistently ready. All my time at SCWTTC was spent learning INDUSTRY welding standards.

I went into my new job with an easy transition because they teach you to mimic the field exactly. I did the aerospace welding program and I would return in a heartbeat. The school, the scheduling, and the program is carefully designed to help you progress consistently and challenge you.

Camarillo, CA   

If you need certification for welding, this is the place to do it. This isn't a school where you fiddle your thumbs for weeks and then barely learn the basics. Jesse Guzman is an amazing instructor. The other instructors, are equally qualified to teach. They're encouraging and always available to help you when you need it. They train with students one-on-one. This school is a second home and a family. In one-and-a-half months I was received my TIG 6G Stainless Steel certification as well as my TIG 6G Chromoly certification. If it wasn't for SCWTTC, I'd still be attending to acquire more certs. I will definitely be returning for more classes in the following summer/winter breaks. 5/5

Oxnard, CA   

No need to worry if you have no prior experience just schedule a tour and see why the school has a extremely positive feedback from pervious students. I started off with no welding experience whatsoever before applying to this school. Now I'm confident in my welding capabilities.

The staff and teachers are really helpful throughout the process on getting you started. I took the automotive welding program and I enjoyed it a lot. I learned how to tig and mig weld different types of materials and use equipment that I wouldn't have had access to otherwise.

Port Hueneme   

Currently finishing up the general welder course at SCWTTC. Overall it's a great experience. The instructors have helped me learn everything I know about welding.

I can’t recommend this school enough

Ventura, CA   

Southern California Welding Training and Testing Center is a great place to get certified. Get hands-on training, one-on-one with the welding instructor. All welding processes: TIG, MIG, and Stick

Oxnard, CA   

I'm happy to have attended SCWTTC for my general welding program and stoked to have graduated. My education here has given me opportunities to go anywhere in the nation with the skills I've acquired.

SCWTTC is amazingly convenient. Mr. Guzman is an expert instructor who pays attention to his students, takes the time to explain everything, listens very well and is an excellent communicator. I love that Southern California Welding Training and Testing Center is affordable and has open enrollment. The front desk staff at this location are always friendly and thorough too!

Ventura, CA   

Scwttc is a great welding school!

I had a really great experience with this school. Teachers and staff were excellent and helped me craft my welding skills and pushed me to be better at welding everyday. I would recommend to everyone who is looking to learn how to weld or even if you are just looking to get some practice in to go to scwttc welding school you wont regret it!!!! :)

With little to no experience in welding, I signed up and they taught me everything from setting up the machines to welding in multiple processes and just about every position.

I immediately got a job after finishing. Amazing teachers and school. I'd highly recommend it for anyone wanting to learn how to weld.


I’m currently a senior at Oxnard High School and have been attending SCWTTC school since the beginning of the summer session. I'll be completing my advanced MIG certification class with in the next month. The hands on, one-on-one instruction and flexible hours allow me to continue attending High School as well. I'm currently working towards a welding career in the manufacturing/ production industry and have gained more skill in the last 3 months of attending Southern California Welding Training and Testing Center than any one of my friends attending the other schools. SCWTTC's location is ideal for anyone living in Ventura County. I can hardly wait to graduate from high school and begin my welding career.

Oxnard, CA   

I'm homeless but they work with me.

Jesse at S.C.W.T.T.C. runs a top notch welding facility. New equipment, backed by an American Welding Society certified welding inspector, makes for a facility that is turning out the future of welding professionals.

The industry is hot right now, and the big shots are recruiting right out of his facility. As a student of Jesse’s, he listened to what I had in mind for a career, and tailored my curriculum to insure that the industry was seeking my credentials, apposed to me hoping to fit into a company.

Great Staff. Fun environment. Amazing instructors.
