Student Testimonials

Sabrina Castrillon, REALTOR®

"Attending the C21 Union Real Estate School was an incredible journey! Dave was not only knowledgeable but also incredibly supportive. With engaging discussions and hands-on activities, every session was both informative and enjoyable. Thanks to the Real Estate School, I was prepared and very excited to start my career in real estate!"

Rachel L., Student

"Just started a new adventure by taking my real estate classes here to earn my license! The process for joining is easy and affordable. Dave is amazing and extremely knowledgeable! He provides great insight into Real Estate as a career. I can't wait to take the State test...I'm confident I'll be passing on the first try with the support of this team!"

James W., Student

"Dave is a true master of his craft with a proven track record of over 40 years in the industry. I'm in my 3rd week of the real estate school and drive over an hour each way as opposed to selecting another program because of his reputation. I would highly recommend anyone making the small investment to get started if you enjoy selling."

Harmen S., REALTOR®

"This place is great if you want to start your career in Real Estate. Definitely recommend everyone come check it out. Dave's a great person to know."

Rafael Lizarde, Student

"I started to take a course to get my real estate license with David Sheerin and boy was I blown away. I thought it was going to be a very lengthy, boring course. Wrong!!! It is very interactive and informative. It doesn't only make you think about selling houses, it makes you think of what's going into the process of being an agent. I recommend this to all trying to get in the field."

Rebekah S., Student

"I have to say, I was initially wary of joining an in-person class when deciding to enroll in a real estate course. I was comparing several schools online and in-person, and selected Amber Century 21 to move forward with getting my real estate license because of the Yelp reviews and after speaking to the instructor Dave on the phone... Dave gives you all the materials you need to earn your required certificates and the weekly classes go over the "real life" experience you need to know when getting into the real estate world. This is far more knowledge you will get compared to any online course! Plus, when you call Dave he will answer your call or call you back in a few minutes. He is very hands on and wants to help you succeed. Dave is always in the office during the week and for the weekly classes he comes in early and stays late to discuss questions you may have. He answers personal real estate questions you have or questions you may have from the book!"

Camy K., Student

"Getting a real estate license had been on my mind for a very long time, then a colleague who attended this school recommended me to join, it was either that or do an online course but I am very glad I chose to enroll with Dave and take his class. Dave is one of the most straightforward teachers I have ever had the pleasure of having and really cuts the BS out of all the material and gets straight to the point, and it's because of this I look forward to attending class. All the agents are also very nice and a pleasure to talk with, it's clear there is a degree of excellence to which everyone in the office holds up to."

Toyia P., Student

"Positive office atmosphere very encouraging. I love taking real estate courses there I'm learning a lot and enjoying myself. I love David Sheerin sense of humor and the way he breaks down real estate when he's teaching. I can't wait to get started with my journey in real estate."

Darling P., Student

"I started taking classes a month ago to obtain my real estate license. Dave is an amazing teacher that brings value and charisma to a class that can otherwise be information overload. The overall support from the staff is very encouraging that this line of business is the right choice and suitable career for me. I love it here and I could not recommend it enough!"

Betty L., Student

"After many discussions and back and forth about becoming a Real Estate Agent, I Finally dove in! I will say the classes are great and bring a lot to the table! Not to mention the professor Dave S. is very knowledgeable and entertaining. Having a professor with extensive background helps guide you to becoming the best agent out there. The pace of the class and the guidance flows smoothly. I recommend coming in a get it done what do you have to lose!"

Elijah Z., Student

"Very pleased with the Wednesday night class. Dave teaches you exactly what you need to know and lets you also learn on your own. Great first step into Real Estate as well as offering future career opportunities. Great place !!"

Nanci J., Student

"I typically don't write reviews, but I just have to gush over Dave Sheerin's Century 21 Amber Realty certification course. If I could give Dave 6 stars I would! He is a genuine, knowledgeable, down-to-earth, and funny instructor. His classes teach you exactly what you need to pass the state board, as well as be a top real estate agent. Not to mention, the price is affordable. I am very confident I will pass the state test thanks to Dave's teachings. Huge thanks to Dave for passing your wealth of knowledge on to me. 6-stars! Highly recommended!"

Jakai L., Student


Look forward to attending my weekly classes here because they are so informative and fun.
Everyone is so eager to teach you all the tricks of the trade here to be successful real estate professionals
We live in the South Bay and have heard nothing but great things about AMBER REALTY so we decided to go in and check it out we met David and we were so extremely impressed by him and his personality and excitement to teach that we knew this was the place that was going to give us the tools that we needed in the California Real estate market to succeed and profit from something we loved to do.

We checked out many schools for this and simply made the best decision possible after talking to others that went other routes and dropped out and gave up.

David keeps you engaged in the learning process


Trained pros on the way"

T H., Student

"One of the best classes in South Bay Area!! The instructor, Dave Sheerin, has the knowledge and expertise to help you pass the Real Estate exam. The classes are fun and entertaining but also informative with a ton prep information to help you get ready for the big test. Sarah, the receptionist, is very friendly and helpful with helping you fill out the necessary documentation(s).

Thank you!"

Tyler C., Student

"I had originally planned to take an online course, but was lucky enough to have a friend push me into taking the course with Dave at Century 21 Amber: I am glad I did. Dave is definitely something else, but in a good way. He keeps the material real and engaging and tells the class what we need to know straight out. His direct style and candidness is something I really appreciate it. I would definitely recommend taking this class if you are on the fence between in person and online. I'm thankful I went here because every week I look forward to classes and walk away with new knowledge."

Tennille Allerheiligen, REALTOR®

"I decided to change career paths after 16 years of IT sales and knew Real Estate was my next endeavor. After signing up for Dave's class, I knew I was in good hands. It is not the boring text book class to help you pass the test, it's Dave's intelligence & experience that got me motivated to pass the test. If he has this passion, why couldn't I? Yes, there are a lot of Real Estate companies to teach and work for, but I wasn't looking for any real estate company to work for.... I wanted the best! A well-known name/Brand like Century 21 backed by a phenomenal broker who's guidance, expertise and great sense of humor has helped me tremendously. I'm forever grateful for this much needed change. Thanks Dave!!"
