Career Journey

Operating Experience

Most recently served as CEO of LK MShare, a portfolio of Civictech communications brands (Mudshare and SendNexus) serving political and non-profit clients. Led the acquisition and initial operating stages, collaborating with the former owner to ensure the business was profitable and positioned for success despite cyclicality and dependency on political clients. Successfully exited in 2024.

Prior to that, co-led Lionfield Capital, representing a syndicate of private equity, family offices, and high-net-worth individuals. Built a comprehensive deal-sourcing machine, identifying dozens of high-quality proprietary and brokered opportunities, which successfully culminated in an acquisition.

Investment Banking

Spent 12 years at Seale Associates, an elite boutique investment bank based in Washington, D.C., focused on middle-market M&A. Advised on 30+ transactions totaling over $3 billion in aggregate enterprise value.

Worked with Fortune 500 companies including Cemex, Tyco International (now Johnson Controls), Arca Continental, Airxcel, and Coca-Cola bottlers, as well as dozens of family-owned businesses navigating complex strategic decisions across industries ranging from healthcare to mining to security to consumer goods.

Although working with sophisticated executives at multinationals was incredibly educational, I was most inspired when I worked with self-made families and founders who managed 'tiny-but-mighty' enterprises. I am often impressed by the transformational impact these companies have on local communities and the personal impact on their employees.

Other Experience

Started my career at PricewaterhouseCoopers (Audit & Consulting) and also co-founded Heladagen, a startup venture.

Education

MBA, B.A. Finance & Accounting from Brigham Young University

A More Intimate Note

Why Angular Partners?

I launched Angular Partners driven by a strong desire to be "in the movie, not just watching the movie" and knowing that I can have a greater impact on this world managing and growing small-medium enterprises than doing anything else. I seek to inspire and lead others by example, and aspire to bring my experience and character to businesses where I can add value.

Florida is Home

After 12 years of living in Washington, D.C., I made the decision to relocate to South Florida to be closer to family and grow my own, which is something I have been excelling at (3 kids in 5 years, sigh…). I have a five-year-old son, a three-year-old daughter, and a newborn daughter, plus a rockstar wife who keeps me on my toes.

Values That Shape Everything

As a proud immigrant American, I have been blessed with the opportunity to build a professional career in this extraordinary country where hard work pays off. However, as much as I value grit and perseverance, I value humility and integrity even more.

In striking difference to my role as an investment banker, I previously served as a permanent missionary (1 year) and volunteered and lived (5 months) at a center for orphaned and victimized infants. These experiences shaped my life and the way I conduct myself personally and professionally. I strive to always lead with integrity and empower others to be successful.
