I wasn’t sure what to look for when looking for a business coach but after my first meeting with David, I knew I had found it. His knowledge and wisdom are unparalleled. He makes the process approachable. He pushes you to grow and guides you in all the areas you’re unsure of. After just 3 meetings with him, my business had its best month yet. I knew I needed some direction and focus and I got that and so much more. If you’ve been looking for a coach, book him NOW! You’ll thank yourself!

As a fiery, passionate Italian business owner, I knew I needed a coach who wasn’t afraid to push me out of my comfort zone, call me out when I was wrong, and still encourage me in a way that actually worked. That’s exactly what I found with David Yassa. I’ve been working with David for almost two years, and during that time we finally broke through the biggest roadblock I had been stuck at in my business for years. The growth we experienced was not incremental — it was transformational. In the second half of 2025, we had three of our best months ever. Even more impressive, during the final two months of the year — a period that is historically very slow for us — we generated nearly one-third of our total income for all of 2024. David has a rare ability to balance accountability, strategy, and encouragement. He doesn’t just help you get where you want to be — he helps you get where you need to be. I cannot recommend him highly enough. David Yassa of The Growth Coach of Greater Portland is, without a doubt, the only business coach you need if you’re serious about real, lasting growth.

Before I found David, I had met with a handful of business coaches who did not meet my expectations. When I finally met with David I told him that I had one more year in me to see if I could make it work, but the stress was not worth it. Its going on three years now and my revenue and profit have doubled, I feel like I have a solid plan and not just vague advice. I feel like I can be myself with David, which includes arguing with him, or expressing the raw authentic ups and downs of business ownership. He is always able to pull me out of the hole and move us forward with a plan. I honestly would not be where I am with out him and would 100% recommend him to anyone who wants to get serious about their business.

David has been an immense help with my business in Portland. He has helped streamline business operations to increase efficiency and revenue production. He has helped double my monthly revenue over the last few months. I was trapped in a solo operation mindset for a couple years, and he’s helping change the lense that I see the world and business through. I now have my first employee and I’m keeping them busy. Business coaching is not a destination for me, its a journey…and thus far with David helping my Fiancé and I with business it’s been a very informative one, and I couldn’t be happier with the outcome. Thanks David!

David Yassa spent the day with our team to educate us on how to use our personality traits and personal values to advantage in the workplace. This workshop was valuable beyond description for me personally. In the following weeks I have been able to gain more and more insight of myself as a leader, and how my values can effect the team. I highly recommend this service to any business owner who wants to build an emotionally intelligent and highly productive power team! Thank you David for the investment in our team, and your continued support of my business! I would recommend you to anyone who is looking to grow their business, or grow their skills as a leader in business!

If 10 stars was an option, I’d click all 10. With David’s coaching and guidance, my business has grown more than I expected within only 6 months of working together. I didn’t expect to hire another employee for another 1-2 years, yet 1 new addition was made last month and will likely need another before the years out. If you want to take your business to the next level and have a coach who’s genuinely invested and above all EXCITED to jump right in and help you and your business, call David. I guarantee it’ll be one of the best investments you’ll ever make!

Unfortunately, our education does not teach us how to succeed in business, close a deal, or lead a winning team. David has a proven track record of helping others succeed. He has personal professional experience where he helped grow an existing business with much of what he teaches. I highly recommend David’s services!

I met with David about 3 months ago. After implementing just a few of the small changes he’d suggested for my business I have started to notice some positive results. David is passionate about his work and genuinely wants to see others succeed. If you are struggling to see growth in your business, let the professional step in. David will listen to your story and your needs and help you make some positive changes to help you achieve the goals you’ve always intended to meet.

Smart people hire a coach. Geniuses hire David Yassa. A coach is put in place to discover the perfect conditions for client development so that magic can happen and success blossoms. David Yassa, The Growth Coach Greater Portland, and quite possibly the most recognizable business coach in Oregon, pilots clients through effective systems, studying the client, getting a feel for where they are on their journey, revealing goals, and designing a roadmap to ultimate victory. David creatively motivates those around him, minimizing self-doubt, and generating confidence with sincere enthusiasm. His unique talent helps discover a client’s untapped potential unlike any other business coach out there. If you don’t want to settle, if mediocre is a word you don’t want in your vocabulary, if you want to be driven, held accountable, and pushed just a little outside your comfort zone to get to that next level of greatness, then make no mistake of hiring anyone other than David Yassa.
