Additional Information

I am celebrating 5 decades in the securities Industry. I am both a FINRA Arbitrator and the designated securities expert witness for the CA State Bar. I am a consulting expert in litigation and arbitration having testified in 25 states involving securities, insurance and annuities. Since 1991, I have been retained over 1000 times and have testified in 365 arbitrations before NASD, FINRA, JAMS, PSE, AAA and PSE along with attending and testifying in over 100 mediations. In addition, I have qualified and testified before the L.A. Federal Court along with State Courts in L.A., Orange, Fresno and San Diego. My case track record stands at 328 wins and 37 losses. From a long-standing banking background in corporate finance to underwriting and investment banking and real estate experience, I bring a strong knowledge of modern portfolio theory through the teaching of hundreds of retirement financial planning seminars at the corporate level. It is my goal to bring a refreshing perspective into the securities expert witness testifying arena that combines objective comprehensive analysis with effective communication skills. Historically, I have represented claimants 65% and respondents 35% to achieve a modicum of balance in my profession. All of my securities licenses are current and include Series, 7, 24, 63, 65, 79 and 99 along with Variable Contracts. My CA Life and Disability Insurance license is also active. While inactive, I also passed the Series 27 and held a California Real Estate Agent's license. I was formerly an Outside Business Activities compliance officer with LightPath Capital in Southlake, TX
