David became my coach at an incredibly tumultous time in my life. He has done a great job of helping me get through all of it, sort it out, apply techniques to deal with different stresses, and come up with creative ways for me to be successful and challenge myself. I would gladly recommend David to anyone looking for a business/life/career coach.

The perspective work you facilitated gave me a whole new outlook on life. It’s brought excitement and energy back in, helped me tap a deeper well of energy I didn’t know was there. Thank you, thank you, thank you.

David is a very strong coach; the type of coach that won’t let you get away with accepting anything less than your true potential.

I began working with Dark Matter Consulting, because I wanted to take my career to the next level but lacked a clear vision for how to proceed.  DMC helped by:

  • Holding me accountable to my own goals
  • Helping elicit strategy and vision that I could not easily articulate
  • Provided insight based on his real-world experience

The outcome of our working together was a much better job and much greater job satisfaction.  He helped me figure out what I really wanted to do and then find that job.  I am deeply grateful.

David is a very insightful coach. He really helped me get out of my rut and clarify what I want in my career. I can’t recommend him highly enough!

—Keith Harkleroad


David helped me create a foundation of which to begin my job search. I was “stuck” and needed help moving forward. By working with David, I was able to:

  1. identify my strengths or gifts
  2. incorporate my them into my resume
  3. articulate my strengths in my resume and networking meetings
  4. screen potential opportunities to ensure it was a “fit”

I feel more confident as I move forward in my search. Thanks, David!

I met David in the summer of 2009. I hired him as my career coach. Just by talking with him over the phone I knew he was a man of high integrity and personable. Over the next three months David challenged me in ways that I have not been challenged before. David is an expert in his field and very creative. If you need a jump start in your job search or just want to learn more about yourself I would highly recommend David as your coach. He will be there today as well as tomorrow and the rest of your life. Pete Stanley, CFO The Homeland Security Foundation of America.

I was lucky to attend a few trainings David facilitated at General Growth. The manner, content, organization and delivery mode of professional development courses made an unforgettable impression on me. David was very responsive to the audience, what made the classes very interactive and enjoyable indeed. He is a great coach, intelligent and very nice person to work with! I would highly recommend David as a professional in coaching and training development.

—Anastasia Terskova, Administrative Assistant – International, General Growth Properties


Dave is a true professional with the highest of ethical standards. He is a delight to work with as he and consistently brings innovative ideas and concepts to the table for consideration. Additionally, Dave is a very effective coach he listens well and has a thriving desire to let people get to the “hart of the matter” with a mixture of humor, determination and insights. 

As a trainer Dave has outstanding platform skills with the uncommon ability to make the complex simple, the hard truth easier to take and the bland exciting. 

I have supreme confidence in Dave’s ability and would recommend him without hesitation.
