Strategic Portfolio Management

Cash Management

Capital Appreciation

Asset Allocation

Cash Management Portfolio

Cash management is an integral part of any overall investment strategy.  Management of client cash is aimed at supporting client income needs and preserving capital. We use conservative fixed income securities like certificates of deposit, U.S. Treasury notes, and bond funds to deliver returns over and above basic bank deposits while maintaining preservation of invested principal.  Our Cash Management Portfolio can be stand alone or integrated into our Capital Appreciation and Asset Allocation strategies.

Capital Appreciation Portfolio

Invest as a Business Owner™

As stewards of our client's capital, we believe a stock portfolio of outstanding companies purchased at reasonable prices is the best approach to growing wealth.

When we invest in a company stock we taking ownership of a well run and profitable company.  We are silent partners gladly allowing company management to grow their business at high expected rates of return.  The goal is to build wealth through capital appreciation as well as company dividends.  

We take a long term view of these investments and are less concerned about short term volatility and market movements.  When prices are temporarily depressed and our valuation outlook remains favorable, we are eager buyers of these companies, and when prices are extremely high we take profits. 

To Paraphrase Warren Buffett

Everyone knows their price, few know their value.
