Ken Wah Testimonial

Zach is one of the best coaches around, period. Through Zach’s programs I’ve been able to get promoted, launch a business on the side, land a new job (which was another promotion), and be a better partner to my wife because I was able to do all of that without getting burned out. For those that are interested in the numbers, that is 2 promotions and a $50k increase in salary in less than a year. To say that I’ve ROI’d on my investment in Zach’s programs would be a massive understatement. I’m so thankful to have Zach as a Coach and Mentor.

“Fantastic!  I’ll tell you what it is… it’s a combination of emotional intelligence, and a kind of clarity in the way Zach is, and the way he works, and the way he talks, that engineer types can relate to.  At the same time, there is all those people skills, fantastic!”

I experienced Zach’s amazing thirst for knowledge, discernment, and ability to apply his insights. I love to see that all he has learned is now being used to help others. Zach is sincere, genuine and willing to roll up his sleeves to help you succeed.”

“Zach is one of the most thoughtful engineers and leaders I have ever met. He is very passionate about shaping careers of his own and also helping others big time. He is my go-to person for all of my career advice! He is a servant leader and will always set his bar high! It’s easy to work with a “let’s get it done” attitude person like Zach.”

Zach is a wonderfully motivating coach. His 8-week coaching program has taught me a lot of new skills and mindsets that I will be able to use for the rest of my life. I have experienced a complete shift from when I started the program to where I am now.”

Ulli Hoff

Systems Engineering Manager, ARTISAN VEHICLES



During one of the first modules of the program, a real life-changing event happened for me.  I realized… I was unhappy because I was living my life outside of my purpose.  It was instantaneous… my relationship with my wife, and my coworkers, has improved 1000%.  I have full clarity now on where I want to reach in my career, and how I’m going to reach it.”

Aaron Hensler

“I was lost… I didn’t know what my future would be.  I can honestly say after three months with OACO and Zach’s program in engineering leadership, that my life is completely different… And I’m happy!  I don’t dread Mondays anymore.

John Real

Anuja Kelkar

Vivek Koul

“I had a lot of anxiety around interviewing… I’d failed some interviews in the past and was pretty disheartened. After working with Zach, … I completely changed my mindset and I was able to turn the interview equation around in my favor. I ended up nailing my interviews, and getting the job of my dreams!

Eric Melz

Promoted to Senior Director of Engineering, SEARCHSTAX

“For me [the Lifestyle Engineering Blueprint] was transformative. It gave me the courage to realize that I could do all these things that you only see in movies or hear about in the news. I realized through going through the journey with OACO, that that person can be me. That person can be you!”

Andy MacDonald

Promoted to Founder & CEO, VoxSomnia

“I’ve been an engineer and engineering manager for around 30 years… I have been through lots of leadership and management and professional development… and I can say that immediately I was touched by this program… You won’t regret it. It will be one of the best things you do for yourself.

Tim Silk

“I was mostly expecting the program to help me figure out how to advance to the next level in my career, but soon enough I found out that it is so much more than that. It helped me widen my horizons to look at my life as a whole, and that has made me a happier and more fulfilled person. The program has given me lots of clarity, and the confidence to take big steps.“

Hakan Berk

Senior Software Engineering Manager, GOOGLE

“When Zach first explained Lifestyle Engineering to me, I was actually feeling pretty frustrated and confused as to how to progress in my career. Growing in community with other members of Lifestyle Engineering, my eyes have been opened. I’ve found that I have a lot more drive, focus, and even happiness in my job!”

Kylie Mccollum

Promoted to Senior Engineer, WHIRLPOOL

“I thought things were going okay until I realized that I’m stuck, and actually I was going backwards. After OACO, I landed a job in a different company, there was a good increase in the base salary, a bonus, RSUs, a Director title, and it really worked out for me.”

Kevork Dikramanjian

Promoted to Director of Product Engineering, CADENCE DESIGN SYSTEMS

“This program has really helped with my confidence. Zach is passionate about helping others learn. He sees that bigger picture I struggle to see. I can’t recommend this program highly enough. I promise you’ll be challenged, you’ll grow, you’ll learn a lot… and also you’ll make a new friend with Zach, who genuinely will care about you and want to see you succeed.”

Mike Vriezema

Matt Sevey

“I got into a rut, and the last couple of years have been difficult. Zach assured me that he could help me, and he did. I have more energy. I really enjoy what I’m doing more. I have more confidence.

It’s really a lifestyle change that you get through the [Lifestyle Engineering Blueprint].”

Lance Paxson

Senior Production Manager, FCC INDIANA

“Working with Zach has brought about positive change in all areas of my life, beyond just helping me enhance my career. I’ve become bolder, more decisive, more confident, and much more aware of my own psychology. I would recommend working with Zach to anyone who wants to become the best possible version of themself.”

JT Whitman

Operations Supervisor, SKIDMORE PUMP

“What it came down to was having the courage to say no to what I was currently doing. This type of help is useful for anyone who feels lost in your career, or maybe it’s just less than ideal.  It is always helpful to have outside coaching to push you in the right direction.  It’s something that I will forever appreciate.”

Jason Schneeman

Promoted to Sustainability Engineering Manager, CARHARTT

“In order to move forward and grow leaps and bounds, I needed three things.  One, a personal 1-on-1 coach to meet my needs.  Two, set very specific goals.  And three, have group accountability. 

I got all those things with the Lifestyle Engineering family.

Ben Donnelly

Telecommunications Engineer, WE CONNECT LLC

“I strongly recommend working with Zach and the OACO Lifestyle Engineering Blueprint.

It is a fun group, and it is a group that has like-minded people who have been in similar situations where we can share with each other our experiences, and experience growth together.”

Hansel Ramathal


“Fear and indecision were taking over my life.

Now today, my biggest breakthrough after working with Zach, is that I’m here with clarity in regards to my life purpose, I’m facing my fears, and I have the energy and focus I need to keep up with work and with my family.

Hector Garcia

Promoted to Engineering Manager, WHIRLPOOL

“Recently, I found myself out of a job… At first I was skeptical, I wasn’t sure a program like [OACO’s] would really help me for my career… Almost immediately as I started… I had more results, better results, I had more confidence, I was feeling much better during the process. It was a success, I found a new job!”

Carlos Tejada

Senior Engineer, SHERWOOD VALVE

“Initially I was skeptical, but very early on I was already sold, because I was able to benefit from the insights I gathered.  Through the exercises and challenges, it led to a breakthrough in my personal development. Anybody who feels they are stuck in their career, I think this program will be very beneficial.

Heemeng (Chris) Foo

Promoted to Director of Quality, ROCKET LAWYER

“I had always had coaches growing up playing sports, but had never really thought about having a coach for life and career. 

If you’re looking to find that work-life balance, and establish your own values and the vision for your career, I highly recommend you reach out to Zach and join the Lifestyle Engineering family.”
