This might come as a shatter to your ego but I've met some GG reps that were just as embarrassing with MY clients wondering WTF? But to be fair, I have also met some very solid GG reps that I was impressed with. Same goes for LCA. Some I wonder how they ever got hired. Others I'm highly impressed with. This is true of every large company.
It's typical when two companies converge that company cultures clash. GG was MUCH different than LCA is. At LCA it's all about $, who cares that you are valued in your offices or seen as a leader in the genetic community? Who cares if your clients look to you for those answers? Who cares if you have the same training and knowledge base as genetic counselors? It really doesn't matter a fig if you can't produce. LCA WILL fire you and replace you with someone who can do both. If you want to survive here, it won't be about being a resource...it will be about you showing them you can perform and increase revenue in an intense fast paced sales environment and market, MONTHLY. I don't think it's fair, but it certainly separates the weak willed from the strong. You either can hack it or you can't. If it's not for you, then by all means get out while your numbers don't head south! It's a totally different selling environment than what you are use to.
Good luck with your decision. Not everyone is the same type of "salesperson".
